    public static void main(String args[]) {

        int length, width, area, perimeter;

   

        Scanner in = new Scanner(System.in);

        System.out.println("Enter length of Rectangle");

        length = in.nextInt();

        System.out.println("Enter width of Rectangle");

        width = in.nextInt();

        // Area of rectangle = length X width

        area = length*width;

        // Perimeter of rectangle = 2 X (length X width)

        perimeter = 2*(length + width);

        System.out.println("Area of Rectangle : "+ area);

        System.out.println("Rectangle of Rectangle : "+ perimeter);

    }

}

OutputEnter length of Rectangle 4 Enter width of Rectangle 5 Area of Rectangle : 20 Rectangle of Rectangle : 18
