In life, square meters are usually referred to as "square meters" or "squares" for short. 1 square means 1 square meter = 1 meter x 1 meter.
For example, a room with a length of 306.5cm and a width of 346.5cm has an area of 10.60225 m2.
Solution: area S= length x width = 306.5cm x 346.5cm = 3.065m x 3.465m =10.620225m2.
2, the square of a number:
The square of a means a×a, abbreviated as a, or it can be written as a× a (the first power of a multiplied by the first power of a equals the second power of a).
For example: 4×4= 16, 8×8=64, what is the plus sign? .
Extended data:
1, the unit of area is square meter, square decimeter and square centimeter. The transformation relationship between them is:
1 m2 = 100 square decimeter = 10000 square centimeter
1 cm2 =0.0 1 cm2 =0.000 1 m2.
2, the area formula of common graphics
(1) rectangular area S= length x width
(2) Square area S= side length × side length
