The first thing we must do for this case is find the area.
"room with walls 14 feet long"
Therefore, the area is given by:
A = (14) * (14)
A = 196 feet ^ 2
Then, the number of pails of plaster are given by:
n = 196/97
n = 2.02
Rounding off we have:
n = 2
Answer:
you would need to buy 2 pails of plaster to cover the ceiling of a room with walls 14 feet long
