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

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 <stdio.h>

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;
}
