1. Создайте абстрактный класс Shape в котором есть два
абстрактных метода double calculateArea() и double calculatePerimetr().
2. Создайте класс Point в котором есть два свойства double x
double y.
3. Создайте классы которые описывают 2
геометрические фигуры (они должны быть подклассами
Shape), при этом они в качестве свойств должны содержать
классы Point.
