Solution in JAVA (judge verdict: Accepted)


import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

class Main
{
  public static void main(String[] args) throws IOException
  {
    BufferedReader br =
    		new BufferedReader(new InputStreamReader(System.in));
    String str = br.readLine();
    
    
    StringTokenizer st =
    		new StringTokenizer(str, " ");

    String tate = st.nextToken();
    String yoko = st.nextToken();  

    int tateNum = Integer.parseInt(tate);
    int yokoNum = Integer.parseInt(yoko);
    
    int men = tateNum * yokoNum;
    int enshu = (tateNum + yokoNum)*2;
    
    System.out.println(men + " " + enshu);

  }
