Inheritance (Write code using eclipse and output screen)
Implement a subclass Square that extends the Rectangle class. In the constructor, accept the x- and y- positions of the centre and the side length of the square. Call the set location and set Size methods of the Rectangle class. Also supply a method getArea that evaluates and return the area of the square. Write a sample program that asks for the side length and centre, and then prints out the square (using the toSring method that you inherit from Rectangle) and the area of the square.
