How many square meters is a square with a side length of 1 m? It can also be regarded as a square with a side of several meters.

A square with a side length of 1 m and an area of1m 2 can also be regarded as a square with a side length of 10 decimeter.

Reason: The square area formula is side length × side length, so the square area with side length 1 m is 1 m2, and the decimeter ratio is 10, so 1 m = 10 decimeter.

First, the nature of the square.

1, two groups of opposite sides are parallel respectively; All four sides are equal; Adjacent sides are perpendicular to each other.

2. All four angles are 90, and the sum of internal angles is 360.

3. Diagonal lines are perpendicular to each other; Diagonal lines are equal and equally divided; Each diagonal bisects a set of diagonal lines.

4. It is both a central symmetrical figure and an axisymmetric figure (with four axes of symmetry).

5. A diagonal line of the square divides the square into two isosceles right triangles, and the included angle between the diagonal line and the side is 45; The two diagonal lines of a square divide it into four congruent isosceles right-angled triangles.

Second, the length of the unit conversion

1, 1 m = 10 decimeter1m =100 cm1m =1000 mm.

2. Corresponding area unit: square meters.

3. Corresponding unit of volume: cubic meters.

The traditional length units in China are: Li, Zhang, Chi, Inch, Ten-day, Qi, Fu, Zhi, Qi, Bu, Chang, Ya, Yan, Ji, Rail, Luo, Millimeter, Li and fen. The basic transformation relationship is as follows:

1 ft = 10 ft; 1 ft = 10 inch; 1 inch = 10 points; 1 = 10%;

1 sheet ≈ 3.33m; 1 ft ≈3.33 decimeter; 1 inch ≈3.33 cm;

1km = 1000m； 1 meter (m) = 100 cm; 1 cm =10mm

1 Li = 150 sheets = 500m; 2 Li = 1 km (1000 m).
