You have been given an incomplete class called Shape. Complete the following steps.

Complete the Shape class by including a getter and setter for its attribute

Create two new child classes, Rectangle and Triangle. These child classes should both have an additional attribute called height. Create constructors, and getters and setters.

Create a new method in Rectangle and Triangle called getArea$().$ This method should return the area of each shape

The area of a rectangle is width x height, and the area for a triangle is $($width x height$)/2$

Inside the main method, create both a Triangle and a Rectangle, and print the area of each.
