Answer:

45 square feet

Step-by-step explanation:

Area of square and area of rectangle:

Area of square = 81 square feet

   [tex]\sf \boxed{Side \ of \ square = \sqrt{area}}[/tex]

                             [tex]\sf = \sqrt{81}\\\\ = \sqrt{9*9}\\\\ = 9 \ feet[/tex]

height = 5 ft

length of wall = 9 ft

Area of one wall = length * height

                            = 9 * 5

                            = 45 square feet
