Solution in C# (judge verdict: Accepted)

using System;

class TestClass {
	static void Main(string[] args) {
		string str = Console.ReadLine();
		string[] array = str.Split(' ');
		float x = float.Parse(array[0]);
		float y = float.Parse(array[1]);
		float a = x * y;
		float b = x * 2 + y * 2;
		Console.WriteLine(a.ToString() + " " + b.ToString());
	}
