Question

Perimeter of the rectangular playing field is 470 yards. the length of the field is 5 yards less than triple the width, what are the dimensions of the playing field

Answer 1

P = 2(L + W)
P = 470
L = 3W - 5

470 = 2(3W - 5 + W)
470 = 2(4W - 5)
470 = 8W - 10
470 + 10 = 8W
480 = 8W
480/8 = W
60 = W <==== width is 60 yards

L = 3W - 5
L = 3(60) - 5
L = 180 - 5
L = 175 <==== length is 175 yards
