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

Solution in C# (judge verdict: Accepted)

using System;



 class Program
 {
     static void Main(string[] args)
     {
         double area,perimeter;
         String nyuryoku;
         nyuryoku = Console.ReadLine();
         string[] data = nyuryoku.Split(' ');
         area = Double.Parse(data[0]) * Double.Parse(data[1]);
         perimeter = 2 * (Double.Parse(data[0]) + Double.Parse(data[1]));
         Console.WriteLine("{0} {1}",area,perimeter);
     }
 }
