Question

An 8 by 8 ft wall has 4 by 5 ft windows. The area of the three windows is what percent of the area of the entire wall including the windows

Answer 1

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)
