Question

If the perimeter of a rectangle is 54 yards and the length is 3 yards longer than the width, then what is the width?

Answer 1

width = 12 yards

Explanation:

width: x

length: x + 3

perimeter: 54

x + x + (x + 3) + (x + 3) = 54

4x + 6 = 54

subtract 6 from both sides

4x = 48

x = 12

width: 12

length: 12 + 3 = 15
