Find Perimeter of a triangle

  • Last Updated : 24 Nov, 2021

Given side (a, b, c) of a triangle, we have to find the perimeter of a triangle. 

Perimeter : 
Perimeter of a triangle is the sum of the length of side of a triangle.

Perimeter of a triangle

where a, b, c are length of side of a triangle.
Perimeter of a triangle can simply be evaluated using following formula : 
perimeter = (a + b + c)



Examples :  

Input : a = 2.0, b = 3.0, c = 5.0
Output : 10.0


Input : a = 5.0, b = 6.0, c = 7.0 
Output : 18.0

C++




// A simple C++ program to find the perimeter
// of triangle
#include <iostream>
using namespace std;
  
// Function to find perimeter
float findPerimeter(float a, float b, float c)
{
      
    // Formula for finding a perimeter
    // of triangle
    return (a + b + c);
}
  
// Driver Code
int main() 
{
    float a = 2.0, b = 3.0, c = 5.0;
    cout << findPerimeter(a, b, c);  
    return 0;
}

C




// A simple C program to find the perimeter
// of triangle
#include <stdio.h>
  
// Function to find perimeter
float findPerimeter(float a, float b, float c)
{
    // Formula for finding a perimeter of triangle
    return (a + b + c);
}
  
// Driver Code
int main()
{
    float a = 2.0, b = 3.0, c = 5.0;
    printf("%f", findPerimeter(a, b, c));  
    return 0;
}

Java




// Java program to find perimeter
// of triangle
class Test {
    static float findPerimeter(float a, float b, float c)
    {
        // Formula for Perimeter of triangle
        return (a + b + c);
    }
  
    // Driver method
    public static void main(String[] args)
    {
        float a = 2.0, b = 3.0, c = 5.0;
        System.out.println(findPerimeter(a, b, c));
    }
}

Python




# Python Program to find a perimeter
# of triangle
  
# Function to find perimeter
def findPerimeter(a, b, c):
  
    # Calculate the perimeter
    return (a + b + c)
  
# Driver Code    
a = 2.0
b = 3.0
c = 5.0
print(findPerimeter(a, b, c))

C#




// C# program to find perimeter
// of triangle
using System;
  
class Test {
      
    static float findPerimeter(float a, 
                           float b, float c)
    {
          
        // Formula for Perimeter of triangle
        return (a + b + c);
    }
  
    // Driver method
    public static void Main()
    {
        float a = 2.0f, b = 3.0f, c = 5.0f;
          
        Console.WriteLine(findPerimeter(a, b, c));
    }
}

PHP




<?php
// A simple PHP program 
// to find the perimeter
// of triangle
  
// Function to find perimeter
function findPerimeter($a, $b, $c)
{
      
    // Formula for finding a 
    // perimeter of triangle
    return ($a + $b + $c);
}
  
    // Driver Code
    $a = 2.0; 
    $b = 3.0;
    $c = 5.0;
    echo findPerimeter($a, $b, $c);
      
// This code is contributed by anuj_67.
?>

Javascript




<script>
  
// JavaScript program to find perimeter
// of triangle
function findPerimeter(a, b, c)
{
      
    // Formula for Perimeter of triangle
    return (a + b + c);
}
  
// Driver Code
let a = 2.0, b = 3.0, c = 5.0;
  
document.write(findPerimeter(a, b, c));
  
// This code is contributed by code_hunt
  
</script>

Output : 

10.0
