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 str = br.readLine();
        String[] strarr = str.split(" ");
        
        int num1 = Integer.parseInt(strarr[0]);
        int num2 = Integer.parseInt(strarr[1]);
        System.out.println(num1*num2 + " " + (num1+num2)*2);
    }
