Implement an Abstract Method

The abstract class Shape declares an abstract method Area with no body. Provide the body in the Rectangle subclass so it returns Width * Height. An abstract method MUST be implemented by any concrete subclass. Do NOT write a Main method.

For new Rectangle(3, 4) the program prints the output shown in Expected Output.

Expected Output:

12↵

= newline. The output ends with a newline — print one after the last line.
