Here's how you could write the program using multiple inheritance.

However, as the others have said, this isn't TRUE multiple inheritance in the sense of inheriting from multiple base classes. Instead, the Rectangle class inherits from one base class (Shape) and implements one interface (IArea):

using System;

class Shape
{
public double Height { get; set; }
public double Width { get; set; }

public Shape(double height, double width)
{
Height = height;
Width = width;
}
}

interface IArea
{
double Area { get;}
}

class Rectangle : Shape, IArea
{
public double Area
{
get { return Height * Width; }
}

public Rectangle(double height, double width): base(height, width)
{
}
}

class Program
{
static void Main()
{
Rectangle rect = new Rectangle(2, 3.5);
Console.WriteLine(rect.Area); // 7
Console.ReadKey();
}
}

Apply intermediate object-oriented language skills. that's the subject

But , you have a way to implement multiple inheritance using interfaces. you can achieve multiple inheritance through interfaces.

Multiple inheritance is not possible in cases of classes.
