Answer 2

Answer:

9 inches

Step-by-step explanation:

A square has an area of 81 in^2

A = s^2

81 = s^2

Take the square root of each side

sqrt(81) = sqrt(s^2)

9 = s

The side length is 9 inches

A square has a perimeter of 36 in

P = 4s

36 = 4s

Divide each side by 4

36/4 = 4s/4

9 = s

Each side is 9 inches
