Question

donna wants to paint the ceiling of her restaurant. the ceiling is in the shape of a square. its side lengths are 55 feet. suppose each can of paint will cover 275 square feet. how many cans will she need to paint the ceiling?

Explanation:

Step1: Calculate ceiling area

The area of a square is $A = s^2$, where $s = 55$ feet. So $A=55^2= 3025$ square - feet.

Step2: Determine number of cans

Divide the total area by the area covered by each can. Let $n$ be the number of cans. Then $n=\frac{3025}{275}=11$.
