More about Square

General

The area is the magnitude of the geometric shape in two-dimensional space. It is used in mathematics, medicine, engineering and other sciences, for example, in calculating the cross section of cells, atoms, or pipes, such as blood vessels or tap pipes. In geography, the area is used to compare the sizes of cities, lakes, countries and other geographical objects. The population density calculations also uses the area. The population density is defined as the number of people per unit area.

Units

Square meters

The area is measured in the SI system in square meters. One square meter - square square, with one meter side.

Single square

A single square is a square with the parties to one unit. The unit square is also equal to one. In the rectangular coordinate system, this square is in coordinates (0.0), (0.1), (1.0) and (1,1). On the complex plane of the coordinate - 0, 1, i. and i.+1, where i. - imaginary number.

AR

AR or weaving, as a measure of the square, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks when hectare is too large. One AP is 100 square meters. In some countries, this unit is called otherwise.

Hectare

In hectares, real estate are measured, especially land plots. One hectare is 10,000 square meters. It is used since the time of the French revolution, and applies to the European Union and some other regions. As well as AR, in some countries hectare is called differently.

Acre

In North America and Burma, the area is measured in acres. Hectares are not used there. One acre is 4046.86 square meters. Initially, Acre was determined as an area that a peasant with a harness from two oxes could have been plowed in one day.

Barne

Barna are used in nuclear physics to measure cross-section of atoms. One barne is equal to 10⁻² ⁸ square meters. Barne is not a unit in the SI system, but adopted to use in this system. One barne is approximately equal to the cross-sectional area of \u200b\u200bthe uranium core, which the physicists were jokingly called "huge, like barn." Barn in English "BARN" (pronounced Barn) and from the joke of physicists This word was the name of the unit of Square. This unit originated during the Second World War, and liked the scientist, because its name could be used as a code in correspondence and telephone conversations within the Manhattan project.

Calculation of Square

The area of \u200b\u200bthe simplest geometric shapes are found by comparing them with a square of the famous area. It is convenient because the square area is easy to calculate. Some formulas for calculating the area of \u200b\u200bgeometric shapes shown below are obtained in this way. Also for calculating the area, especially the polygon, the figure is divided into triangles, calculate the area of \u200b\u200beach triangle according to the formula, and then fold. The area of \u200b\u200bmore complex figures is calculated using mathematical analysis.

Formulas for calculating the area

• Square: Side in a square.
• Rectangle: Work of the parties.
• Triangle (known side and height): The work of the side and height (distances from this side to the edge), divided by half. Formula: A \u003d ½AHwhere A. - area, a. - side and h. - Height.
• Triangle (two sides and angle between them are known): The work of the sides and sinus of the corner between them, divided by half. Formula: A \u003d ½AB sin (α), where A. - area, a. and b. - Parties, and α - the angle between them.
• Equilateral triangle: Side, squared, divided by 4 and multiplied by a square root of three.
• Parallelogram: The work of the side and height measured from this side to the opposite.
• Trapeze: The sum of the two parallel sides, multiplied by height, and divided into two. Height is measured between these two sides.
• A circle: The product of the square of the radius and π.
• Ellipse: The product of the semi-axle and π.

Calculation of surface area

Find the surface area of \u200b\u200bsimple bulk figures, such as a prism, you can scan of this figure on the plane. The scan of the ball is so impossible to obtain. The surface area of \u200b\u200bthe ball is found using the formula, multiplying the square of the radius by 4π. From this formula it follows that the area of \u200b\u200bthe circle is four times less than the surface of the surface of the ball with the same radius.

Surface Square Some Astronomical Objects: Sun - 6.088 x 10) Square kilometers; Earth - 5,1 x 10⁸; Thus, the surface area of \u200b\u200bthe Earth is about 12 times less than the surface area of \u200b\u200bthe Sun. The surface area of \u200b\u200bthe moon is approximately 3.793 x 10 ° C for square kilometers, which is approximately 13 times less than the surface area of \u200b\u200bthe Earth.

Plan meter

The area can also be calculated using a special instrument - a planimeter. There are several types of this instrument, for example polar and linear. Also, the planimeters are analog and digital. In addition to other functions, it is possible to enter into digital plan meters, which facilitates the measurement of objects on the map. The plan meters the distance traveled around the perimeter of the object being measured, as well as the direction. The distance traveled by the plan meter parallel to its axis is not measured. These devices are used in medicine, biology, technician, and agriculture.

Theorem on the properties of the area

According to an isoperimetric theorem, of all figures with the same perimeter, the largest area of \u200b\u200bthe circle. If, on the contrary, compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the side of the geometric shape, or a line that denotes the boundaries of this figure.

Geographic objects with the largest square

Country: Russia, 17,098,242 square kilometers, including sushi and water space. The second and third in the country area is Canada and China.

City: New York is a city with the largest area of \u200b\u200b8683 square kilometers. The second area of \u200b\u200bthe city is Tokyo, which occupies 6993 square kilometers. Third - Chicago, with an area of \u200b\u200b5498 square kilometers.

City Square: The largest square holding 1 square kilometer is located in the capital of Indonesia Jakarta. This is the Square Medan Merdec. The second largest area of \u200b\u200b0.57 square kilometers - Praza-Duz-GiSoras in Palmas, in Brazil. Third largest - Tiananmen Square in China, 0.44 square kilometers.

Lake: Geographers argue whether the Caspian Sea is a lake, but if so, then this is the largest lake in the world with an area of \u200b\u200b371,000 square kilometers. Second on the Lake Square - Lake Top in North America. This is one of the lakes of the System of the Great Lakes; Its area is 82,414 square kilometers. The third in Square - Lake Victoria in Africa. It covers an area of \u200b\u200b69,485 square kilometers.

The need to measure the distance and land area exists with those distant times when ancient people began to move through the territories, use the soil areas for growing plants, separating the territory for the existence of their tribe. Units of measurement passed a centuries-old path. Their names and values \u200b\u200bchanged.

Examples that have come down to us Russian units of measurement of lengths can be called: mile, mile, sage, Arshin, Cup.Square in Russia was measured: a square vest, decade, square soot.

1960 was the year of holding the eleventh General Conference on Measures and Sighs. It participants approved the international system of units of si. 7 main, additional and derivative units of measure were adopted.

The modern metric system is applied, practically, in all states of the planet. According to the system, the main unit of measurement of length is the meter, and the square square square.

Where hectares and weavers are used

The standard use of hectares in Russia is a measurement of land plots. However, the official units of the system are used for the same purpose. C - square meters.

In most cases, the calculation of the land area with hectares is carried out to determine land tax and land share. To do this, after measuring the site, it is calculated from its area and transferred to points that are translated into the personal coefficient. The calculus of the area in hectares will also be needed in areas of land planning, urban planning and forestry.

Do not cost without measuring the area in hectares in sports. For example, the calculation of the field area to all the well-known and beloved American game - rugby, occurs exclusively in hectares. No less interesting fact: a football field where international matches are held, it has a recommended size - 105 per 86 meters and an area of \u200b\u200b0.714 hectares.
The calculation of the area of \u200b\u200bthe site in the weave is used for sale and buying land.

What is 1 hectare

Hectar (designation: Russian-speaking - ha, international - ha; from hecto- and ar) - a unit that is measured area (not included in the SI system). The size of the hectare is equal to the square of the square, the side of which is 100 m. Exists in the legal and metric system. In the Russian Federation, the unit of measurement is allowed to use without limitation of the term and with a scope of use in rural and forestry.

The size of hectares in square meters

The area of \u200b\u200bthe land plot, where and the length, and the width is equal to the hundred meters - this is 1 hectare, it is 10,000 meters in a square. If you know the size of the area necessary for the calculation (length and width), then determine the number of hectares in the area is simple enough.

To do this, take the handle, paper and calculator, and make simple calculations:

1. Determine the area area. To do this, it is enough to multiply the length of the area to the width.
2. If the result is more than 10,000 square meters, then your portion is greater than one hectare.
3. To accurately determine the number of hectares, divide the result obtained in the first step per 10,000.

Remember! On one square kilometer, 100 sections of 1 hectare can be positioned.

What is weaving

Weaving - This is a conversational word that occurred from a numerical "hundred". Saying "weaving the Earth," means a plot whose area is 1ar.

Ar (russian designation a) - This is a unit with which the area is measured. AR is not included in the International System SI and implies an area of \u200b\u200bequilateral quadrangle with a side of 10 meters. It is the official unit for measuring the area in the French Republic.

1 A \u003d 100 meters square \u003d 0.01 hectares.

In order to imagine this distance, make from 12 to 14 average steps, then make a rotation of 90 degrees and repeat the performed. The resulting square is weaving the Earth. Also weselves are called the hundredth of something.

Taking this type of land calculus is convenient for sale and construction, and when sowing garden and garden sites.

How many across hectares in hectare

For accurate calculations of the land area, you need to know the amount of acres in hectare. One hectare is one hundred acres.

In order to translate the amount of across hectares, there are two ways:

• The first method: divide the amount of acres per 100. The resulting number is the area of \u200b\u200bthe site in hectares.
• Second: multiply the amount of across 0.01.

If after conversion the number of hectares is less than one, then write this area more convenient in square meters. For this, the number of hectares is multiplied by 10,000.

In order not to make a mistake in the calculation, remember the relationship:

• 1 s. (weaving) \u003d 100 meters square \u003d 1 AR \u003d 0.0001 kV. km.
• 100 s. (acres) \u003d 10,000 square meters. \u003d 1 ha \u003d 100 AR \u003d 0.01 kV. km.

For a regular dachanka, it makes no sense to acquire a large number of land. He has a lot of place for a full-fledged holiday. But the farmer will need a plot. Properly calculated hectares and weave will help you identify land tax and land share.

In addition, the order of the mandatory use of units S. It is stated in the current 8.417-2002 interstate standard in Russia, which lists the units of physical quantities permitted to use, their international and Russian designations are given and the rules for their use.

International System Units - The most used system of units in the world both in everyday life and in science and technology. Currently S. Adopted as the main system of units by most countries of the world and is almost always used in the field of technology, even in those countries in which traditional units are used in everyday life.

S. Determines 7 basic units of physical quantities and derivatives of units (abbreviated - units S. or units), as well as a set of consoles.

S. Also establishes standard abbreviated designations of units and the rules for the recording of derivative units.

The main units of C:

• kilogram (kg, kg) - Unit of Mass
• meter (m, m) - unit length
• second (C, S) - time
• amp (A, A) - Electric Current Unit
• mole (mol, mol) - a unit of substance
• kandela (CD, CD) - Unit of Light
• kelvin (K, K) is 1 / 273,16 part of the thermodynamic temperature of the triple water point:
  1. degree Celsius (° C) - A widespread temperature measurement unit is used in SI along with Kelvin
  2. clearing in degrees Celsius:

Within S. It is believed that the main units have an independent dimension, that is, none of them can be obtained from others.

Derivatives are obtained from the mains using algebraic actions, such as multiplication and division. Some of the derived units in S. Awarded our own names, for example, a unit of radians.

From January 1, 2018, the exact boundaries of the site should be recorded in the cadastral passport, since it is impossible to buy, sell, lay, or donate land without an accurate description of the boundaries. This is as regulated by the amendments to the Land Code. And the total audit of the borders on the initiative of municipalities began from June 1, 2015.

From March 1, 2015, the new Federal Law "On Amendments to the Land Code of the Russian Federation and individual legislative acts of the Russian Federation" (N 171-FZ dated June 23, 2014, in accordance with which, particular, simplified the procedure for the repurchase of land in municipalities &You can get acquainted with the main provisions of the law.

Regarding the registration of houses, baths, garages and other buildings on land owned by citizens, will improve the situation a new country amnesty.
