It is: 4*7 = 28 cm
All four sides of a square are equal in length, therefore: area = length of a side squared length of a side = √[area] length x 4 = perimeter If the area is in cm² the length will be in cm.

Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.
P = 20 cm
P = 24 cm
It is: 4*8 = 32 cm
It is: 4*7 = 28 cm
All four sides of a square are equal in length, therefore: area = length of a side squared length of a side = √[area] length x 4 = perimeter If the area is in cm² the length will be in cm.
