a rectangular parking lot has a length that is 10 yards greater than the width. the area of the parking lot is 200 square yards.find the length and the width
the equation you use is:
w^2+10w-200 = 0
w = -20 or 10
it has to be positive so the answer is 10.
The width is 10 yards and the length is 20 yards
