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: Runtime Error)

using System;

namespace Rectangle
{

	class Rectangle
	{
        static void Main(string[] args)
        {
            string tmp;
            int x;
            int y;
            int area;
            int length;

            tmp = Console.ReadLine();

            x = int.Parse(tmp.Substring(0, 1));
            y = int.Parse(tmp.Substring(2, 1));

            area = x * y;
            length = (x + y) * 2;
            Console.WriteLine(area + " " + length);
            
		}
	}
