Please answer the following question in Java.

Assume Rectangle is a class that inherits from the Polygon class. Both classes have a custom toString implementation. Rectangle has a getArea method, but Polygon does not. Given the following reference variable declaration and object assignment:

Polygon poly = new Rectangle();

What would happen given each of the following two lines of code? Briefly explain your answer.

System.out.println(poly); double area = poly.getArea();
