Solution in C# (judge verdict: Accepted)

using System;

class Program
{
    static void Main(string[] args)
    {
        var input = Console.ReadLine();
        string[] tmpinput = input.Split(' ');
        int[] intinput = Array.ConvertAll<string, int>(tmpinput, delegate (string value) {return int.Parse(value); });
        int output1 = intinput[0] * intinput[1];
        int output2 = (intinput[0] * 2) + (intinput[1] * 2);
        Console.WriteLine(output1+" "+output2);
    }
