C++ Exercises: Find the area of any triangle using Heron's Formula
C++ Basic: Exercise-18 with Solution
Write a program in C++ to find the area of any triangle using Heron's Formula.
Pictorial Presentation:
Sample Solution:
C++ Code :
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
float side1, side2, side3, area, s;
cout << "\n\n Find the area of any triangle using Heron's Formula :\n";
cout << "----------------------------------------------------------\n";
cout<<" Input the length of 1st side of the triangle : ";
cin>>side1;
cout<<" Input the length of 2nd side of the triangle : ";
cin>>side2;
cout<<" Input the length of 3rd side of the triangle : ";
cin>>side3;
s = (side1+side2+side3)/2;
area = sqrt(s*(s-side1)*(s-side2)*(s-side3));
cout<<" The area of the triangle is : "<< area << endl;
cout << endl;
return 0;
}
Sample Output:
Find the area of any triangle using Heron's Formula : ---------------------------------------------------------- Input the length of 1st side of the triangle : 5 Input the length of 2nd side of the triangle : 5 Input the length of 3rd side of the triangle : 5 The area of the triangle is : 10.8253
