Let L = length. Therefore, by given information the width, W, is equal to L-6. Perimeter = 2*length + 2*width or 2L+2W. Substitute in values we get 188 = 2*L + 2*(L-6) Expand: 188 = 2*L + 2*L - 12 Add 12 to both sides and combine like terms: 200 = 4*L Divide both sides by 4: 50 = L The length if found to be 50 feet. The width is then 50 - 6, or 44 feet. We can confirm that the perimeter is 50+50+44+44 feet, or 188 feet.
