Write a statiC method named find that takes as a parameter an array of type Polygon named list. The method should print the
shapes of each polygon that has an area greater than 500 and return their count.
The method prototype is public static int find (Polygon [] list);
Note: assume the array is already declared, populated with data in the main method and ready to be used.](https://content.bartleby.com/qna-images/question/54eb27f5-2063-4e37-8756-87ba442769c5/d7fcf873-fc40-41fd-8599-e76cfb6575f9/84zr55_processed.jpeg)
