The quotient of 15x^4y^2-30x^2y^3+45xy/5xy is ______ When this quotient is divided by ___ , the result is x^3y-2xy^2+3.

Let w be the width of the rectangle. From the given condition above, its length is therefore equal to w + 4. The perimeter (P) of the rectangle is twice the sum of its width and length. With the given,
                                 36 in = 2 x (w + w + 4)
The value of w is 7. The length is therefore 11 inches.
