![Make a class "Shape that stores two values: the name of a shape and its area.
Initially the name of the shape is declared by the user and the area can be set
later using a mutator method setArea The class has a function named
"printing that prints on the screen "ssssssss is a shape with area xxx.xx ";
where "ssssssss" is the name of the shape and "xxx.xx" is the area of the given
shape object in 2 decimal places. Implement an accessor method to enable
accessing the name of the shape.
Shape
Polygon
Create another class named "Polygon" inheriting the "Shape" class with the same
"printing function that prints information of a polygon object as shown in the output sample
in Figure 2 below. A "Polygon stores values of two sides of the defined shape object. This
class also computes and updates the area value of the given shape; whilst constructing a
polygon object; as follows:
• For "Triangle" shape with two sides presenting height and base of a triangle:
area of Triangle = height x base
• For "Rectangle" shape with two sides presenting width and length of a rectangle:
area of Rectangle = length x width
Given the following code of the main tester program and the corresponding sample output; write the implementation of the
two classes "Shape" and "Polygon".
