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 = 2*(a+b);
      System.out.println(area+" "+length);
  }
