Consider the following simple class:

class Rectangle

{

private:

double length, width;

public:

Rectangle ( double l, double w ){ length = l; width = w; }

double area() { return length * width; }

double perimeter(){ return 2* ( length + width ); }

};

Consider the following class that uses the Rectangle class defined above:

class artItem

{

private:

Rectangle canvas;

String title;

};

a) Write a constructor which initializes the canvas, and the title. The constructor

receives a string parameter to initialize the title and the length and width to pass to the

Rectangle copy constructor when creating the canvas object.

b) Write a print method that prints the title and prints the perimeter and the area of canvas

call the methods area and perimeter to get both values.
