You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that has been known for nearly 2000 years. It is called "Heron's Formula".

You can calculate the area of a triangle if you know the lengths of all three sides, using a
formula that has been known for nearly 2000 years. It is called "Heron's Formula". Heron's formula
uses the following two steps to calculate the area of a triangle.
Step 1: Calculate "s" (half of the triangles perimeter): S=
Step 2: Calculate Area: A = √s(sa)(sb)(sc)
By using Heron's formula, write the definition of the function area_of_triangle so that it can work in
conjunction with the following source code.
#include <stdio.h>
#include<math.h>
int main (void)
{
double a, b, c, area;
printf("Enter the sides of triangle\n");
scanf("%lf%lf%lf", &a, &b, &c);
a+b+c
2
area = area_of_triangle (a, b, c);
printf ("Area of triangle = %.21f\n", area);
return 0;
}
You can use sqrt() from math.h header file. Its prototype is: double sqrt (double x);
A sample run of this program is shown in the following figure.
