Answer 1

Area painter needs to cover = 64.5 ft²

Explanation:

We are given the details of the wall:

Length of the wall = 12 ft

Height of the wall = 8 ft

Area of the wall = 12 · 8 = 96 ft²

The dimension of windows are not given, The dimensions of the windows are found from internet, which are given as.

Length of window =
`3(1)/(2)= (7)/(2)=3.5ft`

Height of window =
`4(1)/(2)= (9)/(2)=4.5ft`

Are of window = 3.5 · 4.5 = 15.75ft²

No. of windows = 2

Total area of windows = 15.75 · 2 = 31.5 ft²

Area painter needs to cover:

96 ft² - 31.5 ft² = 64.5 ft²
