Question

A fence encloses a rectangular feild the feild is 4 meters longer than it is wide. the perimeter of the fence is 144 meters. what is the area in square meters

Answer 1

Length (L): w + 4

width (w): w

Perimeter (P) = 2L + 2w

               144 = 2(w + 4) + 2(w)

               144 = 2w + 8 + 2w

               144 = 4w + 8

               136 = 4w

                 34 = w

Length (L): w + 4   = (34) + 4   = 38

Area (A) = L x w

             = 38 x 34

            = 1292

Answer: 1292 meters²
