#include<math.h>
#include<conio.h>
#include<stdio.h>
int main()
{
    float a,b,c,s,area;
    printf("enter the values of a,b,c");
    scanf("%f %f %f",&a,&b,&c);
    s=(a+b+c)/2;
    area=sqrt(s*(s-a)*(s-b)*(s-c));
    printf("the area of a trangle is : %f ",area);
    return 0;
}

OUTPUT:

enter the values of a,b,c 12
36
45
the area of a trangle is : 158.955765

Possible Error: 1) Function ‘sqrt( )’ should have a prototype : You should include ‘math.h’ Header file, And can use ‘sqrt ( )’ and all other mathematical functions.
