# Area of a Square

**Formula:**`A = side`

^{2}

## Introduction to the Area of a Square Calculator

The area of a square is calculated by squaring the length of one of its sides. In this formula, ** A** represents the area of the square, and

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

*side*## Parameter usage:

`side`

= length of one side of the square

## Example valid values:

`side`

= 5## Output:

`area`

= area of the square

## Data validation

The side length should be greater than zero.

## Summary

This calculator takes into account the side length of a square and outputs its area. It is not specific to a particular unit of measurement.
