The Rectangle class is defined as follows:

public class Rectangle {
    private int width;
    private int height;

    public Rectangle(int width, int height) {
        this.width = width;
        this.height = height;
    }

    public int getWidth() {
        return width;
    }

    public int getHeight() {
        return height;
    }

    public int getArea() {
        return width * height;
    }
}

Which of the following properly defines a Square class that is a subclass of the Rectangle class? A Square is a Rectangle and has a width and height that happen to both be the same length.
