Ricky Reed · Answer 1

336 ft²

Step-by-step explanation:

The rectangle is 13 ft long and 8 width that means we have two walls 8 * 9 and two walls 13*9

Total walls area is

2*8*9 + 2*13*9 = 144 + 234 = 378 ft²

then we subtrac, areas of door, closet and windows

3 * 6.5 = 19,5 ft²

3 * 6,5 = 19,5 ft²

2 * 1,5 = 3 ft²

42 ft²

Then area to paint 378 - 42 = 336 ft²
