How much of what your instructor taught you do you remember? Do you have a specific question? How much have you been able to do?

Hello,

Please check out the below sample code to get the expected result.

public class Rectangle
{
    // Attributes
    private double x;
    private double y;

    // Constructor
    public Rectangle(double x, double y)
    {
        this.x = x;
        this.y = y;
    }

    // Set values of X & Y
    public void SetValues(double x, double y)
    {
        this.x = x;
        this.y = y;
    }

    // Get values of X & Y
    public (double, double) GetValues()
    {
        return (x, y);
    }

    // Calculate area
    public double CalculateArea()
    {
        return x * y;
    }
}

Below is the code to create an instance of the class and call its behavior.

class Program
{
    static void Main(string[] args)
    {
        Rectangle rectangle = new Rectangle(5, 10);

        // Get values of X & Y
        (double x, double y) = rectangle.GetValues();
        Console.WriteLine($"X: {x}, Y: {y}");

        // Calculate area
        double area = rectangle.CalculateArea();
        Console.WriteLine($"Area: {area}");

        // Set new values of X & Y
        rectangle.SetValues(8, 12);

        // Get values of X & Y
        (x, y) = rectangle.GetValues();
        Console.WriteLine($"X: {x}, Y: {y}");

        // Calculate area
        area = rectangle.CalculateArea();
        Console.WriteLine($"Area: {area}");
    }
}

Thanks
