How much fencing is required to put up a chain link fence around a 120-yd by 80-yd playground? The perimeter of a rectangle is 120 ft. The two shorter sides add up to 36 ft. What is the length of each of the longer sides?

Solution

48. Dimensions of the play ground = 120x80 yd

Perimeter = 2(l+w) = 2(200) =400 yards

Hence 400 yds of the fencing is required.

49. Perimeter of rectangle = 2(l+w)

=2(l+36) = 120

l+36 = 60

l= 24 feet.

Longer side = 24 feet
