Introduction 

In this Problem Statement we have to calculate the area of triangle using Heron’s Formula

at=√s(s-a)(s-b)(s-c)

where a, b , c are the side of triangle

S =(a+b+c)/2 it is semi Perimeter

There logic is that first of all we are going to take input from the user in order to calculate the value of area of triangle

so see the algorithm for above problem statement

Algorithm of give Problem

Input: Three side of triangle 

Output: Area of triangle using given formula

Step1: Take the side of triangle as input from user let a, b, s.

Step2: Now Calculate the value of S using below formula

            S =(a+b+c)/2

 Step3: Now calculate the value of area of triangle using below formula

          Area = sqrt(S * (S-a) * (S-b) * (S-c));

Note: in order to calculate Square Root we make use of Function Sqrt

from header file math.h

Step4: Print the value of Area

Step5: Exit.

Flow Chart

Program in C language

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

     double a,b,c,at,temp,S;

     printf("Enter the size of side of triangle\n");

     scanf("%lf %lf %lf",&a,&b,&c);

     S=(a+b+c)/2;

     temp=S*(S-a)*(S-b)*(S-c);

     at=sqrt(temp);

     printf("Area of triangle is %3.2lf",at);

     getch();

}
