       float length, width, area, perimeter;

     

       Scanner in = new Scanner(System.in);

       // Input length and width of rectangle

       System.out.print("Enter length of rectangle: ");

       length = in.nextFloat();

       

       System.out.print("Enter width of rectangle: ");

       width  = in.nextFloat();

       

     

       perimeter = 2 * (length + width);

       

       area = length * width;

       

     

       System.out.println("Perimeter of rectangle is " + perimeter + " units.");

       System.out.println("Area of rectangle is " + area + " sq. units.");
