Problem:
Rectangle

Write a program which calculates the area and perimeter of a given rectangle.

Input

The length a and breadth b of the rectangle are given in a line separated by a single space.

Output

Print the area and perimeter of the rectangle in a line. The two integers should be separated by a single space.

Constraints

1 ≤ a, b ≤ 100

Sample Input 1

3 5

Sample Output 1

15 16

Solution in C# (judge verdict: Accepted)

using System;

namespace Rectangle
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			string input = Console.ReadLine();
		
			char[] CharSeparators = new char[] {' '};
			string[] array = input.Split(CharSeparators);

			string array1 = array[0];
			string array2 = array[1];

			int a = int.Parse (array1);
			int b = int.Parse (array2);

			var area = a*b;
			var periphery =(a+b)*2;
			Console.WriteLine (area+" "+periphery);

		}
	}
