-2 inches This is a simple average of 8 data points. All you need to do is add the value of all the data points together, then divide the sum by the number of data points. So (â’4 + â’6 + â’3 + â’1 + 0 + 2 + â’1 + â’3) / 8 = -16 / 8 = -2 S

Length (L): L

width (w): (2/3)L

Perimeter (P) = 2L + 2w

               290 = 2(L) + 2(2/3)(L)

               870 = 6L + 4L

               870 = 10L

                87 = L

width (w): (2/3)L   = (2/3)(87)   = 2(29)   = 58

width = 58 ft, length = 87 ft
