## Area formula of a rectangle

### The area formula for a rectangle is derived by multiplying the length of the rectangle by its width

The area formula for a rectangle is derived by multiplying the length of the rectangle by its width.

Mathematically, the formula for the area (A) of a rectangle is:

A = length * width

In this formula, “length” refers to the longer side of the rectangle, and “width” refers to the shorter side. It’s important to use the corresponding measurements for the length and width when applying this formula.

For example, if the length of a rectangle is 5 units and the width is 3 units, then:

A = 5 * 3

A = 15

So, the area of the rectangle would be 15 square units.

To help visualize, think of an area as the amount of space that fits within the boundaries of the rectangle. By multiplying the length and width of the rectangle, we are essentially finding the total number of square units that fill this space.
