Answer:
11 cans. (GOOD IDEA TO REMEMBER VARIABLES)
Step-by-step explanation:
OK first thing first is to get the area.
<em>"The ceiling is in the shape of a square. Its side lengths are 55 feet."</em>
In area you multiply 2 sides to get the area.
55 (feet) x 55 (feet) = 3, 025 (feet squared)
Now we also have the paint:
<em>"Suppose each can of paint will cover square 275 feet."</em>
Now you are supposed to divide:
3, 025 / 275 = 11
11 cans are needed to paint this ceiling.
