 * C Program to Find Area of rhombus
#include <stdio.h>
int main()
    float diagonal1, diagonal2;
    float area;
    printf("Enter diagonals of the given rhombus: \n ");
    scanf("%f%f", &diagonal1, &diagonal2);
    area = 0.5 * diagonal1 * diagonal2;
    printf("Area of rhombus is: %.3f \n", area);
    return 0;
Program Explanation

In this C program, library function defined in <math.h> header file is used to compute mathematical functions. We are reading the diagonal value of the rhombus using ‘diagonal1’ and ‘diagonal2’ variables. To find the area of a rhombus, the following formula is used.
Area = 0.5* diagonal1 * diagonal2

Runtime Test Cases
$ cc pgm26.c
$ a.out
Enter diagonals of the given rhombus:
 30 40
Area of rhombus is: 600.000
