Use the perimeter formula
perimeter = sum of the sides
side one is x the opposite side is also x
the longer sides are x + 14. So
x + x + 14 + x + x + 14 = 96. Solving you get
4x + 28 = 96 subtract 28 from each side
4x = 68 divide by 4 you get x = 17
therefore the width is 17 and the length is
17 + 14 = 31 the answers are in meters 😋
