Solution in JAVA (judge verdict: Accepted)

import java.io.*;
 
class Main
{
       public static void main (String[] args) throws IOException
       {
 
       BufferedReader br =
        new BufferedReader(new InputStreamReader(System.in));
 
       String str1 =br.readLine();
       String str2[] =str1.split(" ");
       int a =Integer.parseInt(str2[0]);
       int b =Integer.parseInt(str2[1]);
       int c =a*b;       
       int d =2*(a+b);
 
       System.out.println(c + " " + d);
 
    }
