		try {
			BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
			String str = reader.readLine();
			String[] arr = str.split(" ");
			int a = Integer.parseInt(arr[0]);
			int b = Integer.parseInt(arr[1]);
			System.out.println(a * b + " " + (a + b) * 2);
		} catch (IOException e) {
