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 a = scan.nextInt();
        int b = scan.nextInt();

        int area = a * b;
        int cir = (a + b) * 2;

        System.out.println(area + " " + cir);
    }
}
