Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main
{
  public static void main(String[] args)
   {
     Scanner sc = new Scanner(System.in);
     int a = sc.nextInt();
     int b = sc.nextInt();
     int area = a*b;
     int length = (a+b)*2;
     System.out.println(area+" "+length);
     sc.close();
   }
}
