Given side 
of a Decagon, the task is to find out the Perimeter of the Decagon.
Explanation : In geometry, a decagon is a ten-sided polygon or 10-gon. A regular decagon has all sides of equal length and each internal angle will always be equal to 144 degrees.
Examples:
Input : S = 5 Output : The Perimeter of Decagon is : 50 Input : S = 8 Output : The Perimeter of Decagon is : 80
The formula for finding the Perimeter of the Decagon is:
Perimeter = 10 * S where "S" is the side of the Decagon
Below is the program to find perimeter of decagon:
C++
// C++ program to Calculate the Perimeter of a Decagon#include <iostream>using namespace std;// Function for finding the perimetervoid CalPeri(){ int s = 5, Perimeter; Perimeter = 10 * s; cout << "The Perimeter of Decagon is : " << Perimeter;}// Driver codeint main(){ CalPeri(); return 0;} |
C
// C program to Calculate the Perimeter of a Decagon#include <stdio.h>// Function for finding the perimetervoid CalPeri(){ int s = 5, Perimeter; Perimeter = 10 * s; printf("The Perimeter of Decagon is : %d", Perimeter);}// Driver codeint main(){ CalPeri(); return 0;} |
Java
/*package whatever //do not write package name here */// Java program to Calculate the Perimeter of a Decagonimport java.io.*;class GFG {// Function for finding the perimeter static void CalPeri() { int S = 5, Perimeter; Perimeter = 10 * S; System.out.println("The Perimeter of Decagon is : "+ Perimeter); } // Driver code public static void main (String[] args) { CalPeri(); }}//This Code is contributed by ajit |
Python3

PHP
<?php // PHP program to Calculate the Perimeter of a Decagonfunction CalPeri($s) { $Perimeter = 10 * $s; echo "The Perimeter of Decagon is : $Perimeter";} // Driver Code $s = 5; CalPeri($s); ?> |
Javascript
<script>// JavaScript program to Calculate the Perimeter of a Decagon // Function for finding the perimeter function CalPeri() { var S = 5, Perimeter; Perimeter = 10 * S; document.write("The Perimeter of Decagon is : " + Perimeter); } // Driver code CalPeri();// This code contributed by gauravrajput1 </script> |
Output:
The Perimeter of Decagon is : 50
Time Complexity: O(1)
Auxiliary Space: O(1)
