Arectangular quilt is to contain 1900 square centimeters. one side is to be 40 centimeters longer than the other. which statement will allow you to find the length of the quilt?

The area of a certain rectangle can be computed by multiplying the length and the width. That is,
                                  Area = length x width
We let x be the measure of one side of the rectangle. With this representation, the other side is x+40. The expression for area then becomes,
                                  1900 = (x + 40)(x)
