Пожалуйста помогите с лабораторной работе по программированию C++​

class FindRectangleArea { public static void main(String arg[]) { Rectangle rect = new Rectangle(11, 5); System.out.println("Length = " + rect.length); System.out.println("Breadth = " + rect.breadth); System.out.println("Area = " + rect.getArea()); System.out.println("Perimeter = " + rect.getPerimeter()); } } class Rectangle { double length; double breadth; Rectangle(double length, double breadth) { this.length = length; this.breadth = breadth; } double getArea() { return length * breadth; } double getPerimeter() { return 2 * (length + breadth); } }
