Solution in JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.lang.Math;

public class Main {
    public static void main(String[] args) {
        try {
            BufferedReader stdReader = new BufferedReader(new InputStreamReader(System.in));
            
            String line;
            
            while((line = stdReader.readLine()) != null) {
                String[] input = line.split(" ", 0);
                int a = Integer.parseInt(input[0]);
                int b = Integer.parseInt(input[1]);
                
                int area = a * b;
                int round = (a + b) * 2;
                
                System.out.println(area + " " + round);
            }
            stdReader.close();
        } catch(Exception e) {
