How to calculate the square area formula?

1, rectangle: S=axb, {rectangle area = length× width}

2. Square: S=axa{ square area = side length x side length), parallelogram: S=ah{ parallelogram area = bottom × height}

3. Triangle: S=axb+2 (triangle area = bottom x height +2).

4. cuboid surface area: S=2 x(ab+ac+bc), {cuboid surface area = (length× width+length× height+width× height )× 2}.

Square meters (㎡, French: mètre carré, British English: square m2, American English: square m2) are international units of area. It is a common measure in life and work. Definition: The area of a square with a side length of 1m is defined as 1m2, and the area of a plane with any shape is also called 1m2 if it is equivalent to the area of a square with a side length of1m..

Square meter conversion:

1, conversion formula of public land area unit 1 mu =60 square abbot = 6,000 square feet, 1 mu =666.6 square meters?

2. The square meter is mu, and the calculation formula is "add half to the left and move three". 1 m2 = 0.0015mu, for example, how many mu is128m2? The calculation method is 128 plus half of 128: 128+64= 192, and then move the decimal point three places to the left, that is, the mu number is 0. 192.

3. The mu is square meters, and the calculation formula is "divide by three, and move right by three". If you want to calculate how many square meters 24.6 mu equals, 24.6÷3=8.2, which is 16.4 after doubling, and then move the decimal point to the right by 3 places, the square meter is 16400.
