tril and tri$2$ are instances of the Triangle class. Attributes height and base of both tril and tri$2$ are read from input. Then, scaling$\_$factor and scaling$\_$factor are read from input. In the Triangle class, define instance method scale$\_$attributes with self and one integer as parameters to: Assign attribute height with height's current value multiplied by the integer parameter. Assign attribute base with base's current value multiplied by the integer parameter.
