(The Rectangle class) Design a class named Rectangle to represent a rectangle. The class contains: - Two double data fields named width and height that specify the width and height of the rectangle. - A no-arg constructor that creates a rectangle with width 1 and height 1. - A constructor that creates a rectangle with the specified width and height. - The accessor and mutator functions for all the data fields. - A function named getarea () that returns the area of this rectangle. - A function named getPerimeter() that returns the perimeter. Implement the class. Write a test program that creates two Rectangle objects. Assign width 4 and height 40 to the first object and width 3.5 and height 35. 9 to the second. Display the width, height, area, and perimeters of the first object and then the second object
