#include <stdio.h>

float area_of_rectang (float, float);

int main (void)

{

     float length, width;

     float area;

     //Input sides.

     printf ("Input length: ");

     scanf ("%f", &length);

     printf ("Input width: ");

     scanf ("%f", &width);

     //Function call

     area = area_of_rectang (length, width);

     //Print result

     printf ("Area of rectangle: %.2f", area);

     return 0;

};

float area_of_rectang (float length, float width)

{

     float area;

     //Calculate area

     area = length * width;

     //Return area

     return area;

};

Output

Input length: 5.3

Input width: 2.7

Area of rectangle: 14.31
