Solution in C# (judge verdict: Accepted)

using System;

class Program{
    static void Main(string[] args){
        string strValue=Console.ReadLine();
        string[] strValueSplit=strValue.Split(' ');
        int a=int.Parse(strValueSplit[0]);
        int b=int.Parse(strValueSplit[1]);
        
        Console.WriteLine(a*b+" "+2*(a+b));
    }
