Solution in C# (judge verdict: Accepted)

using System;

class Program
{
    static void Main()
    {
                int a, b, men, syu;
                string mozi = Console.ReadLine();
                string[] data = mozi.Split(' ');
                a = int.Parse(data[0]);
                b = int.Parse(data[1]);
            if (1 <= a && b <= 100)
            {
                men = a * b;
                syu = a * 2 + b * 2;
                System.Console.WriteLine("{0} {1}", men, syu);
            }
        }
    }
