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;

public class Program
{
    public static void Main()
    {
        string input = Console.ReadLine();
        string[] split = input.Split(' ');
        int length = Int32.Parse(split[0]);
        int breadth = Int32.Parse(split[1]);
        int area = length * breadth;
        int perimeter = (length + breadth) * 2;
        Console.WriteLine("{0} {1}", area, perimeter);
    }
