Solution in JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Main{

		// TODO ?????????????????????????????????????????????

        try (BufferedReader br = new BufferedReader(new InputStreamReader(System.in))) {
            String line;
            while ((line = br.readLine()) != null&&line.length()!=0) {
            	String[] str=line.split(" ");
            	int a=Integer.parseInt(str[0]);
            	int b=Integer.parseInt(str[1]);

            	System.out.println(a*b+" "+(a*2+b*2));
            	break;
            }
