# Find Perimeter of a triangle

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. where a, b, c are length of side of a triangle.

Perimeter of a triangle can simply be evaluated using following formula : 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 ` ` `  `// 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 Perimter 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 Perimter 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)); ` `    ``} ` `} ` ` `  `//This code is contributed by vt_m.  `
