4 length = 5;
5 width = 10;

6 // Area of rectangle = length * width
7 area = length * width;

8 // Perimeter of rectangle = 2 * (length + width)
9 perimeter = 2 * (length + width);

10 System.out.println("Area of the rectangle is: " + area);

11 System.out.println("Perimeter of the rectangle is: " + perimeter);
12 }
