Each pair of plaster covers 97 square feet of ceiling. how many pails of plaster would you need to buy to cover the ceiling of a room with walls 14 feet long?

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
 
 you would need to buy 2 pails of plaster to cover the ceiling of a room with walls 14 feet long

The answer is 16.64 feetyour welcome
