# Program for Circumference of a Parallelogram

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
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

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)
