Abstract Shape Area

The abstract class Shape declares an abstract method Area() with no body. Every concrete subclass must implement it. Implement Area() in Rectangle so it returns width * height. Do NOT write a Main method.

When the tester creates a Rectangle(3, 4) and prints its Area(), 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.
