public class Main {
    public static void main(String args[]) throws IOException {

    	// ??\??????????????????????????????
		BufferedReader r = new BufferedReader (new InputStreamReader (System.in));
		String s = r.readLine();

		// ??\??????????????????????????????????????§??????
		String[] morse = s.split(" ");

		// ???????????????????????????????????°??????????????????
		int height = Integer.parseInt(morse[0]);
		int width = Integer.parseInt(morse[1]);

		// ??¢???????¨??????????
		int area = height*width;

		// ??¨???????¨??????????
		int rect = 2*(height+width);

		// ?????????????????????
		System.out.println(area+" "+rect);
    }
