Solution in C# (judge verdict: Accepted)

using System;
 
 
namespace Application{
   class Program{
    
    
        public static void Main(string[] args){
             
            string line = Console.ReadLine();
            string[] vals = line.Split(' ');
            int a = int.Parse(vals[0]);
            int b = int.Parse(vals[1]);
             
            Console.WriteLine(a*b + " " + (a*2+b*2));
        }   
   }
