To find the area of any triangle in which values of three sides are given we can use Heron's formula
which is equal to:
C++ Program to find the area of any triangle using Heron's Formula
#include<iostream>
#include<math.h>
using namespace std;
int main()
{
float first,second,third;
float s,area;
cout<<"Enter size of each sides of triangle"<<endl;
cout<<"Enter size for First Side =";
cin>>first;
cout<<"Enter size for Second Side =";
cin>>second;
cout<<"Enter size for Third Side =";
cin>>third;
s = (first+second+third)/2;
area = sqrt(s*(s-first)*(s-second)*(s-third));
cout<<"Area of Triangle= "<<area<<endl;
return 0;
}

Note: To apply Heron's formula there should be values of all three sides of a triangle.
