• Difficulty Level : Medium
• Last Updated : 21 Jun, 2022

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`
