Question

Elena has a rectangular garage floor with a perimeter of 54 feet.
The length of the garage floor is 18 feet. What is the width of the garage floor?

Answer 1

Let the width of the garage floor be represented by x.

Since the perimeter of a rectangle is equal to 2 times the length plus 2 times the width, we can set up the equation:

2(18) + 2x = 54
36 + 2x = 54
2x = 18
x = 9

Therefore, the width of the garage floor is 9 feet.
