C++ Exercises: Calculate area of an equilateral triangle
C++ Basic: Exercise-53 with Solution
Write a program in C++ to calculate area of an equilateral triangle.
Pictorial Presentation:
Sample Solution:
C++ Code :
#include<iostream>
using namespace std;
#include<math.h>
main(){
float s1;
float area;
cout << "\n\n Calculate the area of the Equilateral Triangle :\n";
cout << " ----------------------------------------------------\n";
cout<<" Input the value of the side of the equilateral triangle: ";
cin>>s1;
area = sqrt(3)/4*(s1*s1);
cout<<" The area of equilateral triangle is: "<<area<<endl;
cout << endl;
return 0;
}
Sample Output:
Calculate the area of the Equilateral Triangle : ---------------------------------------------------- Input the value of the side of the equilateral triangle: 5 The area of equilateral triangle is: 10.8253
