Area = Length x width.
The area of the wall is 8 x 8 = 64 square feet.
The area of one window is 4 x 5 = 20 square feet.
The area of the 3 windows is 20 x 3 = 60 square feet.
The percentage would be (area of windows / area of wall) x 100
Percentage = 60/64 = 0.9375 x 100 = 93.75% (round answer as needed)
