Solution in C# (judge verdict: Accepted)

using System;

public class Hello
{
    public static void Main()
    {
        
string[] str = Console.ReadLine().Split();
   int a=int.Parse(str[0]);
    int b=int.Parse(str[1]);

int s,i;
    s=a*b;
    i=2*a+2*b;
    
    
    Console.WriteLine("{0} {1}",s,i);
    
    
    }
