I am assuming that the problem states that you are to reduce both the length and width by the same amount - correct? You are starting with a rectangle that is 40 by 50 or 2000 square feet: 40 * 50 = 2000 If you subtract x feet from both sides, the new area is: (40-x)*(50-x) = 1739 Solve for x. This tells you how many feet to lop off both the length and width. |
