A rectangles length is 2 units more than twice its width. its area is 40 square units. the equation w (2w+2) = 40 can be used to find w, the width of the rectangle.

what is the width of the rectangle?

4 units is the width.

10 units is the length. If we put this in, we get (l*w) 10*4 for the area, which is 40 square units. This is a true statement. Also, 4*2 is 8, and 2 more units than 8 is 10 units.
