Explanation:

To solve this problem, first note that the width of the rectangle must equal:

Now that you know the width and length of the rectangle, apply the area formula:

### Example Question #61 : Geometry

A rectangle has a width of  and a length of  Find the area of the rectangle.

Explanation:

To find the area of a rectangle apply the formula:

This problem provides the measurements for both the width and length of the rectangle.

Thus, the solution is:

### Example Question #61 : Geometry

Find the area of the rectangle shown above.

Explanation:

In this problem you are given the width and perimeter of the rectangle. However, to solve for the area of the rectangle you must first find the length of the rectangle. To do so, work backwards using the formula:

Now that you know the width and length of the rectangle, apply the area formula:
