Question

4. Kenneth needs to repaint a wall in his bathroom. The wall is 8 feet high and 14 feet long. Part of

the wall is covered with tile and he will not paint that part. The part of the wall covered by tile is 14
feet long and 42 inches high. Which expression could Kenneth use to find the area of the part of the
wall he needs to repaint?
a. 148-(42 + 8)
b. 14 * 8 - (42 * 14)
c. 148 -[(42 +12) * 14]
d. 2(14 + 8) -[(42 +12) + 14]

Answer 1

96 * 144 - 168 * 42

Explanation:

So the area of the wall is 96 * 144

And the area of the tiled part is 168 * 42

So it would be 96 * 144 - 168 * 42
