Question 2: Write a class Rectangle, which has two data members, namely, length and width. It has member functions that calculates and prints out, the rectangle's perimeter Q and area (). Write member functions to set and get length and width attributes. You must also provide a default constructor that sets length=0 and width = 0 and a constructor with parameters. Perimeter = 2*(length + width) Area =length * width . In the main program do the following: Create an object of type Rectangle. Read the objects length and width from the user. Print the rectangle's perimeter and Area to the user. . A sample run is given below: Please enter the length and width: 2.2 3.4 Perimeter is : 11.2 Area is : 7.48
