Answer 2

Given:

Length of the wall = 8 ft

Width of the wall = 6 ft

Length of the window = 2 ft

Width of the window = 18 in

To find:

The square feet Jamin planning to paint

Solution:

Area of the wall = length × width

= 8 × 6

Area of the wall = 48 ft²

Width of the window = 18 in

Convert inch to feet.

1 feet = 12 inch

18 inch =
`(18)/(12)=1.5` ft

Area of the window = length × width

= 2 × 1.5

Area of the window = 3 ft²

Area to be painted = Area of the wall - Area of the window

= 48 ft² - 3 ft²

= 45 ft²

Therefore Jamin planning to paint 45 ft².
