Solution in JAVA (judge verdict: Accepted)

import java.io.*;

class Main
{
public static void main (String[] args)throws IOException
{

BufferedReader br =
new BufferedReader(new InputStreamReader(System.in));

String str1 = br.readLine();
String str2[] = str1.split(" ");
int a = Integer.parseInt(str2[0]);
int b = Integer.parseInt(str2[1]);
int c = a*b;
int d = 2*(a+b);
System.out.println( c + " " + d);
}
