Let x = width of the parking lot
2x + 200 = length of the parking lot (being 200 yards more than twice the width)
The area of the rectangular lot is the length*width
so
simplifying...
divide both sides by 2 to simplify
factoring...
possible solutions are x=-500 and x=400. We take x=400 yards as length cannot be negative
so the width of the parking lot is 400 yards and the length is 1000 yards
