Answer:
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
