Answer

Width: 12 feet, Length: 18 feet

Work Step by Step

If the width is x and the length is 6 feet longer than the width, then the length is x + 6. The equation for perimeter is: P = 2l + 2w Substituting our values into the equation, we get: 60 = 2(x + 6) + 2x Solve for x: 60 = 2x + 12 + 2x 60 = 4x + 12 48 = 4x 12 = x The width is x = 12 feet, and the length is x + 6 = 12 + 6 = 18 feet.
