C++ Exercises: Find the area of Scalene Triangle

C++ Basic: Exercise-28 with Solution

Write a C++ program to find the area of the Scalene Triangle.

Pictorial Presentation:

Sample Solution:

C++ Code :

#include <iostream>
#include <math.h>
#define PI 3.14159
using namespace std;

    int main()
    {
    	float side1, side2, ang1, area;
		cout << "\n\n Find the area of Scalene Triangle :\n";
		cout << "----------------------------------------\n";		
        cout<<" Input the length of a side  of the triangle : ";
    	cin>>side1;
        cout<<" Input the length of another side  of the triangle : ";
    	cin>>side2;
        cout<<" Input the angle between these sides of the triangle : ";
    	cin>>ang1;	
		area = (side1 * side2 * sin((PI/180)*ang1))/2;
        cout<<" The area of the Scalene Triangle is : "<< area << endl;
        cout << endl;
        return 0;
    }

Sample Output:

 Find the area of Scalene Triangle :                                   
----------------------------------------                               
 Input the length of a side  of the triangle : 5                       
 Input the length of another side  of the triangle : 6                 
 Input the angle between these sides of the triangle : 6               
 The area of the Scalene Triangle is : 1.56793
