C++ Exercises: Find the area of Scalene Triangle
C++ Basic: Exercise-28 with Solution
Write a program in C++ to find the area of 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
