Answer: 615 ft²
<u>Step-by-step explanation:</u>
There are 4 walls - <em>assume that the floor and ceiling are not being painted.</em>
2 walls are 17 ft by 9 ft ⇒ 2(17)(9) = 306 ft²
The other 2 walls are 18 ft by 9 ft ⇒ 2(18)(9) = 324 ft²
1 window is 3.75 ft by 4 ft ⇒ 1(3.75)(4) = 15 ft²
2 walls + other 2 walls - 1 window ⇒ 306 + 324 - 15 = 615 ft²
50 / 0.40 = 125
To check your answer, 125 * 0.4 = 50
