Length=154yards and width =56yards
Given that perimeter of rectangular playing yard is 440yards=2(L+W)
Length of field is 4 yards less than triple the width i.e Length = (3W-4)
What is perimeter of rectangle?
Perimeter = 2(L+W)
2(L+W)=440....(*)
We have L=(3W-4)
Plug L value in *
2(3W-4+W)=440
2(4W-4)=440
8(W-1)=440
W-1=55
W=56
So W= 56
L=3(56)-4=164
Therefore Length=154yards and width =56yards
