Ilia_Sergeevich [38]

Answer:

45 square feet

Step-by-step explanation:

Area of square = 81 square feet

$\sf \boxed{Side \ of \ square = \sqrt{area}}$

$\sf = \sqrt{81}\\\\ = \sqrt{9*9}\\\\ = 9 \ feet$

height = 5 ft

length of wall = 9 ft

Area of one wall = length * height

= 9 * 5

= 45 square feet
