Solution in C# (judge verdict: Accepted)

using System;


class abc
{
public static void Main()
{
String[] str1 = new String[2];
str1 = Console.ReadLine().Split();

int a = int.Parse(str1[0]);
int b = int.Parse(str1[1]);


int c = a*b;
int d = (a+b)*2;

str1[0] = c.ToString();
str1[1] = d.ToString();

Console.WriteLine(str1[0] + " "+str1[1]);
}
}
