PLEASE HELP!

How do i use the parent Shape class' toString function to implement the Rectangle toString function. It should print out the same information, and in the same format.

#include <iostream>
#include <sstream>
#include <string>

using namespace std;

class Shape
{
public:
	Shape(double w, double h);
	string toString();

private:
	double width;
	double height;

};

Shape::Shape(double w, double h)
{
	width = w;
	height = h;
}

string Shape::toString()
{
	stringstream ss;
	ss << "Width: " << width << endl;
	ss << "Height: " << height << endl;

	return ss.str();
}

class Rectangle : public Shape
{

public:
	Rectangle(double w, double h, int s);
	string toString();

private:
	int sides;

};


string Rectangle::toString()
{
	//
    stringstream ss;
	ss << "Width: " << width << endl;
	ss << "Height: " << height << endl;
	ss << "Sides: " << sides<<endl;

	return ss.str();
}

Rectangle::Rectangle(double w, double h, int s)
:Shape(w,h)
{

    sides= s;
}

//

int main()
{
	double width;
	double height;
	const int sides = 4;

	cin >> width;
	cin >> height;

	Rectangle bob = Rectangle(width, height, sides);
	cout << bob.toString();

	return 0;

For instance:

string Rectangle::toString()
{
	//
    stringstream ss;
	ss <<Shape::toString(); // Note: This is how you call a function of the base class
	ss << "Sides: " << sides<<endl;

	return ss.str();
}
