Answer: public static void randomize(RegularPolygon r){
 int side = (int)((20-10) * Math.random()) + 10;
 int length = (int)((12-5) * Math.random()) + 5;
 // assuming the regularpolygon class has setSide and setLength methods.
 r.set.Side(side);
 r.setLength(length);
The randomize method is used to access and change the state of the RegularPolygon class attributes sides and length. The method accepts the class as an argument and assigns a random number of sides and length to the polygon object.
