1 m2 is the area of a square with a side length of 1 m. If the area of a plane with any shape is equivalent to the area of a square with a side length of 1 m, it is also called 1 m2.

The practical application of 1 m2;

(1)㎡ can be used to measure all kinds of items purchased in daily life. Including the measurement of buying a house and buying tiles.

(2)㎡ can be used to solve and learn mathematical problems, and is also widely used in other disciplines.

(3)㎡ can be used as the abbreviation of square meters in life.

There is a big gap between the square meters and hectares of the expanded data, which is 6.5438+0 million times. Because the hectare is 100 square meter, and there is a square with 10 meter in the middle. The difference between square meters and square meters is 100 times, and the difference between square meters and scenery is also 100 times, so the difference between square meters and hectares is 1000 times. The difference between hectares and square kilometers is 100 times, so one square meter is equal to 0.00005438+0 square kilometers.

These ratios are also expressed in other ways. One square kilometer is equal to 654.38+0 million square meters, and one hectare is equal to 654.38+0 million square meters. One square decimeter =0.0 1 m2, one square centimeter =0.000 1 m2, and one square millimeter equals 0.0000 1 m2.
