Liam Mcpherson · Answer 1

The perimeter of the square is 36cm.

Step-by-step explanation:

The area is found when you multiply the length x width. 9 x 9 = 81. Since a square has equal sides. 9cm would be on the 4 sides. 9 x 4 = 36cm

Akira Owen · Answer 2

36 cm

Step-by-step explanation:

The area of a square is given by

A = s^2

81 = s^2

Take the square root of each side

9 = s

We want the perimeter

P = 4s

P = 4*9

P = 36
