• Difficulty Level : Medium
• Last Updated : 16 Feb, 2023

A square is a flat shape, in one plane, defined by four points at the four corners. A square has four sides all of equal length, and four corners, all right angles (90 degree angles). A square is a kind of rectangle.

Examples :

```Input : 4
Output :16

Input :8
Output :64```

Formula

## C++

 `// CPP program to find ``// the area of the square``#include ``using` `namespace` `std;`` ` `int` `areaSquare(``int` `side)``{``    ``int` `area = side * side;``    ``return` `area;``}`` ` `// Driver Code``int` `main()``{``    ``int` `side = 4;``    ``cout << areaSquare(side);``    ``return` `0;``}`

## Java

 `// Java program to find ``// the area of the square``import` `java.util.*;`` ` `class` `GFG``{``    ``static` `int` `areaSquare(``int` `side)``    ``{``    ``int` `area = side * side;``    ``return` `area;``    ``}``     ` `    ``// Driver Code``    ``public` `static` `void` `main(String[] args) ``    ``{``        ``int` `side = ``5``;``        ``System.out.println(areaSquare(``4``));``    ``}``}`

## Python3

 `# Python3 code to find ``# the area of the square`` ` `def` `areaSquare( side ):``    ``area ``=` `side ``*` `side``    ``return` `area`` ` `# Driver Code``side ``=` `4``print``(areaSquare(side))`` ` `# This code is contributed``# by "Sharad_Bhardwaj".`

## C#

 `// C# program to find ``// the area of the square``using` `System;`` ` `class` `GFG``{``    ``static` `int` `areaSquare(``int` `side)``    ``{``        ``int` `area = side * side;``        ``return` `area;``    ``}``     ` `    ``// Driver code``    ``public` `static` `void` `Main() ``    ``{``        ``int` `side = 4;``         ` `        ``Console.WriteLine(areaSquare(side));``    ``}``}`` ` `// This code is contributed by vt_m`
