1. Problem Description

The problem states that a rectangular playing field has a perimeter of 538 yards. The length of the field is 6 yards less than quadruple the width. We are asked to find the dimensions (width and length) of the playing field.

2. Solution Steps

Let ww be the width of the rectangular field, and ll be the length of the rectangular field. We are given that the perimeter is 538 yards, so
2l+2w=5382l + 2w = 538
We are also given that the length is 6 yards less than quadruple the width, so
l=4w6l = 4w - 6
Now we have a system of two equations with two variables:
2l+2w=5382l + 2w = 538
l=4w6l = 4w - 6
We can substitute the second equation into the first equation to solve for ww:
2(4w6)+2w=5382(4w - 6) + 2w = 538
8w12+2w=5388w - 12 + 2w = 538
10w12=53810w - 12 = 538
10w=55010w = 550
w=55w = 55
Now that we have the width, we can find the length:
l=4w6=4(55)6=2206=214l = 4w - 6 = 4(55) - 6 = 220 - 6 = 214
So the width is 55 yards and the length is 214 yards.

3. Final Answer

The width is 55 yards.
The length is 214 yards.
