Solution in JAVA (judge verdict: Accepted)

import static java.lang.System.out;
import java.util.Scanner;
 
public class Main {
      public static void main(String...args) {
                String str = new Scanner(System.in).nextLine();
                String[] list = str.split(" ");
                String x = list[0];
                String y = list[1];
 
                int a = Integer.parseInt(x);
                int b = Integer.parseInt(y);
 
                int sum = a * b;
                int cm = (a + b) * 2;
 
                out.println(sum + " " + cm);
 
      }
