Question 3: [Programming] Design a class named Rectangle that extends Geometricobject. The class contains: - Two double data fields named width, and length with default values 1.0 to denote two sides of the rectangle. - A constructor that creates a rectangle with the specified width, and length. - The get and set methods for all two data fields. - A method named getarea() that returns the area of this rectangle. - A method named getperimeter() that returns the perimeter of this rectangle. - A method named tostring() that returns a string description for the rectangle, as follows return"Rectangle:Width="+width+"length="+length; - Your code must be fully documented. This includes using Javadoc comments. - Use the following code as a startup for your solution. You only need to implement the Rectangle classStep by Step Solution
