8 1/2 = 8.5
The total are of the 4 walls is:
2*8*8.5 + 2*12*8.5 = 340 ft^2
Since the will be painted 2 times we have:
2*340 = 680 ft^2
The cost for painting 680 ft^2 of walls is:
(680/30)*45.79
The area of the floor is:
8*12 = 96 ft^2
The cost for carpeting the floor is:
6.58*96
Altogether it will cost:
(680/30)*45.79 + 6.58*96 = $1,669.59
The cost of the room will be $1,669.59.
