# Area of a Rectangle

**Formula:**`A = length × width`

## Introduction to Area of a Rectangle Calculator

The area of a rectangle is calculated by multiplying its length by its width. In this formula, ** A** represents the area of the rectangle,

**is the measurement of one of the longer sides of the rectangle, and**

*length***is the measurement of one of the shorter sides. The result is expressed in square units, based on the units used for length and width (e.g., square meters, square feet).**

*width*## Parameter usage:

`length`

= length of the rectangle`width`

= width of the rectangle

## Example valid values:

`length`

= 5`width`

= 15

## Output:

`area`

= area of the rectangle

## Data validation

The numbers should be greater than zero.

## Summary

This calculator takes into account the width and height of a rectangle and outputs its area. It is not specific to a particular unit of measurement.
