C Program to find the Area and Perimeter of a Rectangle using function

Source Code (Finding Area)

#include <stdio.h>

int area(int, int);

int main()

{

    int len, bred, a;

    printf("Enter length of rectangle:-\n");

    scanf("%d", &len);

    printf("Enter breadth of rectangle:-\n");

    scanf("%d", &bred);

    a = area(len, bred);

    printf("The area is %d", a);

    return 0;

}

int area(int a, int b)

{

    int area;

    area = a * b;

    return area;

}

Source Code (Finding Perimeter)

#include <stdio.h>

int perimeter(int, int);

int main()

{

    int len, bred, p;

    printf("Enter length of rectangle:-\n");

    scanf("%d", &len);

    printf("Enter breadth of rectangle:-\n");

    scanf("%d", &bred);

    p = perimeter(len, bred);

    printf("The perimeter is %d.", p);

    return 0;

}

int perimeter(int a, int b)

{

    int perimeter;

    perimeter = 2 * (a + b);

    return perimeter;

}
