Question

You want to paint the ceiling of your bedroom. The area is 140 ft. The ceiling has two square skylights.

Each skylight has a side length of 15/8 feet. How
many square feet will you paint?

Answer 1

132
`(31)/(32)` ft²

Explanation:

First we shall work out the area of 1 skylight. one skylight is 15/8 feet so 15/8 x 15/8 = 3.515625 feet. x this by 2 as there is 2 skylights. So in total, there is 7.03125 feet^2 covered by the skylights. Take this from the original area 140ft - 7.03125 ft = 132.96875 ft^2 or as a mixed number 132
`(31)/(32)` ft²
