Program to calculate area of a triangle

Formula of Area of Triangle:

Area = ( s (s-a) (s-b) (s-c) ) ^ (1/2)
where s = (a+b+c) / 2
a , b and c are the Sides of Triangle.

Statement of C Program: Write a Program to Find the Area of a Triange , given the Three Sides of Triangle:

Source Code

#include<stdio.h>

#include<math.h>

int main()

{

float a,b,c,s=0,area=0;

printf("Enter the length of sides of triangle \n");

scanf("%f %f %f",&a,&b,&c);

s = (a+b+c)/2.0; /* s is semi-perimeter */

area = (sqrt)(s*(s-a)*(s-b)*(s-c));

printf("Area of triangle =\t %f",area);

return 0;

}

Output
