How to calculate the area of a triangle using Heron’s formula in C#

Answer 1

using System;

public class HeronTriangleArea
{
    // Function to calculate area using Heron's formula
    public static double HeronArea(double a, double b, double c) {
        double s = (a + b + c) / 2.0; // semi-perimeter
        return Math.Sqrt(s * (s - a) * (s - b) * (s - c));
    }

    public static void Main(string[] args)
    {
        double a = 6, b = 9, c = 13;

        // Check the validity of the triangle
        if (a + b > c && a + c > b && b + c > a) {
            double area = HeronArea(a, b, c);
            Console.WriteLine("Area of the triangle = {0:F4}", area);
        }
        else {
            Console.WriteLine("Invalid triangle sides!");
        }
    }
}



/*
run:

Area of the triangle = 23.6643
