Since it is a square all sides will be the same. There formula for area is l*w=a. Since l=w and a is given.
let 1 side = x
9=x*x
9=x2
then square root 9 and x2
x=3
So each side is 3 cm.
Each side is 20 cm
260 cm
A square with a side length of 23 cm has an area of 529 cm2
Since its a square, it has four sides and each side is the same length. 12 cm/4= 3 cm per side.
If the perimeter of a square is 30 cm, each side is 7.5 cm and the area is 56.25 sq cm. For a square to have an area of 30 sq cm each side would have to be 5.48cm.
each side would be 15 cm long.
Since a square has 4 sides, if each side is 7.5 cm long, then the perimeter is 4 x 7.5 cm = 30 cm.
Each side is 20 cm
Each side is 6 cm long.
260 cm
Each side is 20.548/4 = 5.137 cm
Each side is: 12.32/4 = 3.08 cm

A square that is 5 cm on each side is a perfect square. It is 25 cm in area which is found by multiplying the length of one side by the base. It's perimeter is the sum of its sides which is 4 x 5 cm = 20 cm.
the surface are of a cube that is 5 cm long, wide, and high is 150 cm^2. Each side of the box is a square measuring 5cm x 5cm, so each side has an area of 25 square cm. A box has six sides, so the total surface area of all six sides is 6 x 25 square cm = 150 square cm.
