Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
public class Main{
    public static void main(String[] args)
   {
	Scanner scan = new Scanner(System.in);
	
	int num1 = scan.nextInt();
	int num2 = scan.nextInt();

	int sum,length;

	sum = num1*num2;
	length = num1*2+num2*2;

	System.out.println(sum+" "+length);

	
    }
