What is important in this problem is the equation for Perimeter
Perimeter = 2Length + 2Width
So 99 = length (l)
374 = 2(99) + 2(w)
374 = 198 + 2w
Subtract
176 = 2w
Divide both sides by 2
88 = w
The Width is 88 yards

The perimeter of a rectangle is 2*L+2*W. Knowing that length is 99, we do 2*99 to get 198.Do 374-198, which is 176, we know that that is twice the length of the width. Therefore the width is 176/2, which is 88.
