Chapter 4.1, Problem 16PPE

To determine

To describe: a real world relationship between the area of a rectangle and its width and to sketch a graph which shows this relationship.

Explanation of Solution

If length of rectangle remains same and width of rectangle varies then area of rectangle also varies. If width decreases then area of rectangle also decreases and width increases then area of rectangle also increases.

The graph which shows this relationship is as follows-

In this graph $x$ axis represents width of rectangle and $y$ axis represents area of rectangle.
