Perimeter Area


Objetive:

Create a program to calculate the perimeter, area and diagonal of a rectangle from its width and height (perimeter = sum of the four sides, area = base x height, diagonal using the Pythagorean theorem). It must repeat until the user enters 0 for the width.


Code:

using System;
public class exercise67
{
    public static void Main()
    {
        double width;
        double height;
        double perimeter, area, diagonal;

        do
        {
            Console.Write("Enter the desired width: ");
            width = Convert.ToDouble(Console.ReadLine());

            if (width != 0)
            {

                Console.Write("Enter the desired height: ");
                height = Convert.ToDouble(Console.ReadLine());

                perimeter = width * 2 + height * 2;
                Console.WriteLine("Perimeter: {0}", perimeter);

                area = width * height;
                Console.WriteLine("Area: {0} ", area);

                diagonal = Math.Sqrt((width * width) + (height * height));
                Console.WriteLine("Diagonal: {0} ", diagonal);
            }
        }
        while (width != 0);
    }
}
