Lisa wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of sever
al rectangles that have the same width and different lengths. She then employed the results and connected them with a line, as shown in the picture. The graph shows the area (in m2) versus the length (in m)
