	public static void main(String[] args)throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String str = br.readLine();
		String[] s = str.split(" ");

		int a = Integer.parseInt(s[0]);
		int b = Integer.parseInt(s[1]);

		System.out.println(a * b +" "+ (a + b) * 2);
