The approximate area of the wall not including the windows is square feet.

Question

Nadine is painting a wall and needs to determine the area of the wall to know how much paint she needs to buy. Nadine’s wall is shown. The circular window has a diameter of 4 feet, and the rectangular window has a length of 6 feet and a height of 4 feet. The approximate area of the wall, not including the windows, is square feet. The box shows 10 ft. for length and 15 ft. for width.

Answer 1

10x15 - 6x4 - pi(4/2)^2

= 150 - 24 - 4pi

=126 - 4pi

= about 126- 4(3.14)

= about 126-12.56

= about 113.44 ft^2
