A rectangle is one of the most common geometric shapes. It is a four-sided figure with four right angles and opposite sides have the same measure. Finding the area of a rectangle is a relatively simple task and is often required in real life situations. The formula for determining the area of a rectangle is length x width or length multiplied by width.

Step 1

Measure the length of the rectangle. The length is the longest side of the rectangle. Write down the measurement so that you will have it when you are ready to use the formula. For example, the long side of a flower bed in the shape of a rectangle could measure 8 feet.

Step 2

Measure the width of the rectangle. This will be the shortest side and is always shorter than the length. Write down the measurement. For example, and using the same flower bed example, the width could measure 4 feet.

Step 3

Multiply the length measurement times the width measurement. These are the two measurements that you found in steps two and three. So, if you multiply 8 feet times 4 feet, you get 32 square feet as the area of the rectangular-shaped flower bed.
