Solution in JAVA (judge verdict: Accepted)

import java.util.InputMismatchException;
import java.util.Scanner;

public class Main{
    public static void main(String args[]){
        Scanner scan = new Scanner(System.in);

        try{
            int a = scan.nextInt();
            int b = scan.nextInt();
            System.out.println((a*b)+ " " +2*(a+b));
        }catch(InputMismatchException e){
            System.out.println(e);
        }
    }
