Program for Circumference of a Parallelogram
• Difficulty Level : Medium
• Last Updated : 24 Mar, 2021

Given the sides of Parallelogram then calculate the circumference.
Examples :

```Input: a = 10, b = 8
Output: 36.00

Input: a = 25.12, b = 20.4
Output: 91.04```

The opposite sides of a parallelogram are of equal length and parallel. The angles are pairwise equal but not necessarily 90 degree. The circumference of a Parallelogram can be computed as sum of two adjacent sides each multiplied by 2. Formula used to calculate circumference of a Parallelogram:
(2*a)+(2*b)

## C++

 `// C Program to calculate the``// Circumference of a Parallelogram.``#include ` `float` `circumferenceparallelogram(``float` `a, ``float` `b)``{``    ``return` `((2 * a) + (2 * b));``}` `int` `main()``{``    ``float` `a = 10, b = 8;``    ``printf``(``"Circumference of a given Parallelogram is : %.2f"``,``           ``circumferenceparallelogram(a, b));``    ``return` `0;``}`
