Programa para la Circunferencia de un Paralelogramo

Dados los lados del paralelogramo, calcula la circunferencia.
Ejemplos: 
 

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

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

Los lados opuestos de un paralelogramo son de igual longitud y paralelos. Los ángulos son iguales por pares pero no necesariamente de 90 grados. La circunferencia de un paralelogramo se puede calcular como la suma de dos lados adyacentes, cada uno multiplicado por 2.
 

Fórmula utilizada para calcular la circunferencia de un paralelogramo: 
(2*a)+(2*b)

// 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;
}
