P = 20cm
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
25cm x 4 sides = 100 cm perimeter
20cm/4sides = 5cm 5cm*5cm = 25cm^2
25cm x 25cm = 625cm
25cm. You take the square root of 625cm2 and you'll get 25cm.
A square with an area of 400 square units has a perimeter of 80 units.
The area of a square is a function of the perimeter of the square.
If the area of a square is 12 the perimeter is: 13.86
