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;

class Tester
{
    static void Main(string[] args)
    {
        string x = Console.ReadLine();
         
        const char Space = ' ';

        char[] delimiters = new char[] { Space };

        string[] result = x.Split(delimiters);

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

        if(1<=a&&a<=100&&1<=b&&b<=100)
        {
            Console.WriteLine("{0} {1}", a * b, a * 2 + b * 2);
        }
    }
}
