Solution in JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class Main {

	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringTokenizer st=new StringTokenizer(br.readLine());

        int a=Integer.parseInt(st.nextToken());
        int b=Integer.parseInt(st.nextToken());

        int menseki=a*b;
		int gaisyu=2*(a+b);

		System.out.print(menseki);
		System.out.println(" "+gaisyu);

	}
