Answer 2

The area of the square can be gotten by using the perimeter of the square to get the length of the square. Then, we use the length to find the area of the square.

Properties of a square.

• All the sides are equal
• All the angles are equal.
• All the sides are parallel to each other.

Therefore,

perimeter of a square = 4l

where

• l = length of square

Therefore,

4l = 20

divide both sides by 4

l = 20 / 4

l = 5 meters

Therefore,

area of the square = l²

where

• l = side length

area of the square = 5²

area of the square = 25 cm²
