Question

Using C# and Microsoft Visual Studio 2017 with Windows Forms Application,

Create an application named ShapesDemo that creates several objects that descend from an abstract class called GeometricFigure. Each GeometricFigure includes a height, a width, and an area. Provide get and set accessors for each field except area; the area is computed and is read-only. Include an abstract method called ComputeArea() that computes the area of the GeometricFigure. Create three additional classes:

• A Rectangle is a GeometricFigure whose area is determined by multiplying width by height.

• A Square is a Rectangle in which the width and height are the same. Provide a constructor that accepts both height and width, forcing them to be equal if they are not. Provide a second constructor that accepts just one dimension and uses it for both height and width. The Square class uses the Rectangle’s ComputeArea() method.

• A Triangle is a GeometricFigure whose area is determined by multiplying the width by half the height.

In the ShapesDemo class, after each object is created, pass it to a method that accepts a GeometricFigure argument in which the figure’s data is displayed.

Explanation / Answer

As per your requirement the below one is solution please follow it

a. A Rectangle is a GeometricFigure whose area is determined by multiplying width by height.

b. A Square is a Rectangle in which the width and height are the same. Provide a constructor that accepts both height and width, forcing them to be equal if they are not. Provide a second constructor that accepts just one dimension and uses it for both height and width. The Square class uses the Rectangle’s ComputeArea() method.

c. A Triangle is a GeometricFigure whose area is determined by multiplying the width by half the height.
