Yes[ ] | No[ ] Shape is a child class. Yes[ ] | No[ ]
Rectangle is a derived class. = Yes[ X] | No[ ] The FindArea() method is an example of polymorphism. = Yes[X ] | No[ ] Shape is a child class. = Yes[ ] | No[X ]
class Rectangle{ private double width; private double length; public rectangle(double w, double l){ width = w; length = l; } public double FindArea(){ return width = length; } } For each statement, select Yes if the statement is true. otherwise, select no.
The length and width data fields do not limit access to their values. = Yes[ ] | No[X] FindArea is a class method = Yes[ X] | No[ ] The values 3.14 and 42.22 can be used as length and width values for the rectangle class = Yes[ X] | No[ ]
