The size of the plane figure occupied by objects is called their area. Area is the size of a plane figure, square meters, square decimeters and square centimeters, which is a recognized unit of area and can be expressed as (m? ，dm？ ，cm？ )。

Area is a quantity indicating the degree of a two-dimensional figure or shape or plane layer in a plane. A surface region is a simulation on a two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness, which is necessary to form a shape model.

Extended data1m2 (1m2) =100dm? (100 square decimeter) = 10000 cm? ( 10000 cm2)= 1000000mm？ (1000000 mm2)

Unit conversion is to convert square meters into square decimeters, square centimeters and square millimeters, and then square the carry between them with units. For example,1m =10dm; 1㎡= 10dm× 10dm = 100dm？ . The rest can be converted by this conversion method.

The application of ㎡ is as follows:

㎡ can be used to measure all kinds of flat objects in life. Including the measurement of buying a house and buying tiles.

㎡ can be used to solve and learn mathematical problems, and can also be widely used in applied problem units of other disciplines.

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