Question

I only need 22. not 21 or 23. what’s the perimeter of 22??

Answer 1

36 ft

Explanation:

22. The square has an area of 81 ft^2

The area of a square is given by

A = s^2

81 = s^2

Take the square root of each side

sqrt(81) = sqrt(s^2)

9ft =s

We want the perimeter of the square

P = 4s = 4*9 = 36 ft
