Solution in JAVA (judge verdict: Accepted)

import java.io.*;

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

 BufferedReader reader =new BufferedReader(new InputStreamReader(System.in));
 String[] line = reader.readLine().split(" ");
 int a = Integer.parseInt(line[0]);
 int b = Integer.parseInt(line[1]);
  
 int area = a * b;
 int areaLength = ( a + b ) * 2;
 System.out.println(area + " " + areaLength);

}
