It is 20 cm

The area of the square cannot be 400 centimetres - it must be 400 square centimetres.If the area is 400 sq cm, then each side is sqrt(400) = 20 cm.
Each side is 20 inches. 20 x 20 = 400 square inches.
Total perimeter is 80 yards. As it is a square, divide the 80 by 4 (as there are 4 sides of equal length). Then multiply: 80 ÷ 4 = 20, 20 x 20 = 400 square yards is the area of the field.
A square with an area of 400m has a side length of 20m. The perimeter of a square of four times the length of one of its sides. Four times 20m is 80m. Therefore, the perimeter is 80m.
A square with a side length of 20 units has an area of 400 square units.

√400 = 20The answer is 20
The area of the square cannot be 400 centimetres - it must be 400 square centimetres.If the area is 400 sq cm, then each side is sqrt(400) = 20 cm.
No. If you double the length of the sides, you multiply the area by 4. For example, a 10x10 square has an area of 100, but a 20x20 square has an area of 400.
Each side is 20 inches. 20 x 20 = 400 square inches.
A square with a side length of 20 cm (80/4) has an area of 400 cm2

Total perimeter is 80 yards. As it is a square, divide the 80 by 4 (as there are 4 sides of equal length). Then multiply: 80 ÷ 4 = 20, 20 x 20 = 400 square yards is the area of the field.
A square with an area of 400m has a side length of 20m. The perimeter of a square of four times the length of one of its sides. Four times 20m is 80m. Therefore, the perimeter is 80m.
400 sqinches (20 x 20)
If a square has a perimeter of 80 meters, then each side is 20 meters in length. (80/4 sides of a square=20) The area of a square is side2, so 20*20 equals 400. The area of a square that has a perimeter of 80 meters is 400 meters2.
