		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		 List<Integer> list = new ArrayList<Integer>();
		 for (String s : Arrays.asList(br.readLine().trim().split("\\s+"))) list.add(Integer.parseInt(s));
		 
		 int a = list.get(0), b = list.get(1);
		 
		 System.out.println(""+(a*b)+" "+(2*a+2*b));
