Question

The length of a rectangle is 6 inches longer than its width. The perimeter of the rectangle is 28 inches. If x represents

the width of the rectangle in inches, which equation can be used to find its value?

Answer 1

Width = 4

Length = 10

Explanation:

Width: x

Length: x+6

2x + 2(x+6) = 28

2x + 2x + 12 = 28

4x = 28-12

x = 16/4

x = 4
