C# program to find the area of a triangle

C# program to find the area of a triangle:

In this post, we will learn how to find the area of a triangle in C#. To calculate the area of a triangle, we need the base and height of the triangle. Once we get both, we can find the area by using the following formula:

Triangle area = (base * height)/2

So, if we have the base and height values, we can find the area of the triangle.

This C# program will take the base and height as inputs from the user and print the area.

C# program:

Below is the complete C# program:

using System;

class HelloWorld {
  static void Main() {
    Console.WriteLine("Enter the base value:");
    double baseValue = Convert.ToDouble(Console.ReadLine());

    Console.WriteLine("Enter the height:");
    double heightValue = Convert.ToDouble(Console.ReadLine());

    double area = (baseValue * heightValue) / 2;
    Console.WriteLine("Area : " + area);
  }
}

Here,

• It is asking the user to enter the base of the triangle. This value is stored in the variable baseValue.
• It is again askiing the user to enter the height of the triangle. This value is stored in the variable heightValue.
• It is calculating the area of the triangle using the above formula and that value is stored in the area variable.
• The last line is printing the area of the triangle calculated.

If you run this program, it will print output as like below:

Enter the base value:                               
31                        
Enter the height:
33                                              
Area : 511.5

By using a separate function:

We can also solve it by using a separate function. This function will take the base and height as the arguments and return the area.

Below is the complete program:

using System;

class HelloWorld
{
  static double findArea (double b, double h)
  {
    return (b * h) / 2;
  }

  static void Main ()
  {
    Console.WriteLine ("Enter the base value:");
    double baseValue = Convert.ToDouble (Console.ReadLine ());

    Console.WriteLine ("Enter the height:");
    double heightValue = Convert.ToDouble (Console.ReadLine ());

    Console.WriteLine ("Area : " + findArea (baseValue, heightValue));
  }
}

Here,

• findArea is a different function that calculates the triangle area.
• We are calling this function from the Main method.
• The other part of the program is same as above.

It will print similar output.
