Consider the following class definition:

class rectangleType
{
public:
         void setLengthWidth(double x, double y);

         void print() const;
         //Output length and width;
         double area();
         //Calculate and return the area of the rectangle;
         double perimeter();
         //Calculate and return the parameter;
         rectangleType();
         //Postcondition: length = 0; width = 0;
         rectangleType(double x, double y);
         //Postcondition: length = x; width = y;
private:
         double length;
         double width;
};

Which of the following class variable declarations is correct?

     rectangle rectangleType;
                                        class rectangleType rectangle;
