Question 579237: A lawn is 90 feet long and 40 feet wide. By cutting along the perimeter, how wide is this border if 1/3 of the grass is cut?

More info: provided solution is 5 feet. Student says answer must be derived by using quadratic formula.
X=width of the border
2(90)(x)+2(40)(x)=(90 times 40)/3
Which then does not result in a constant for a to be used in the quadratic formula. B is 260 and c is negative 1200. Since the constant a is zero, i get a divide by zero using the quadratic formula which means to me the answer is infinite but the provided answer is 5. I have made an error but i can't find it. Please advise.
