The perimeter of a rectangle is the sum of twice the length and twice the width. In algebraic form, here it is:
Perimeter = 2L + 2W
If the length is 80 more than the width, then we just substitute l with W+80:
Perimeter = 2(W+80) + 2W = 200
2W + 160 + 2W = 200
4W = 200 - 160 = 40

W = 10 yards
L = 90 yards
