// Task

// We provide the implementation for a Rectangle class in the editor. Perform the following tasks:

/**
 * Add an area method to Rectangle's prototype.
 * Create a Square class that satisfies the following:
 * It is a subclass of Rectangle.
 * It contains a constructor and no other methods.
 * It can use the Rectangle class' area method to print the area of a Square object.
 * Locked code in the editor tests the class and method implementations and prints the area values to STDOUT.
 */

/*
 *  Write code that adds an 'area' method to the Rectangle class' prototype
 */
