Answer:

length = 95 yards

width = 51 yards

Explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 292 yards

The statement

The length of the field is 7 yards less than double the width is written as

l = 2w - 7

Substitute the expression into the above formula and solve for the width

292 = 2( 2w - 7) + 2w

292 = 4w - 14 + 2w

292 = 6w - 14

6w = 292 + 14

6w = 306

Divide both sides by 6

w = 51

Substitute this value into l = 2w - 7

That's

l = 2(51) - 7

l = 102 - 7

l = 95

Therefore we have

length = 95 yards

width = 51 yards

Hope this helps you
