A worker has a fixed amount of fencing to enclose a rectangular area of land next to a river. The river will form one side of the rectangle. The other three sides will be fenced.
Two rectangles are made above each other. The area enclosed by lower rectangle is shaded with light blue color and labeled as River. The upper rectangle with length smaller than lower rectangle and width more than lower rectangle is made. The upper length of the upper rectangle is labeled x meters. The area enclosed by upper rectangle is shaded with light brown color and labeled as Enclosed area. The right side width of the upper rectangle is marked and labeled as Fencing.
The table models how the area of the rectangle depends on the side length x that is parallel to the river.
What does the x-intercept represent?
