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 Scala (judge verdict: Accepted)

object Main {
  def main(args:Array[String]) = {
    val sc = new java.util.Scanner(System.in)
    val x = sc.nextInt
    val y = sc.nextInt

    println(calcArea(x, y) + " " + calcPerimeter(x, y))
  }

  def calcArea(x: Int, y: Int): Int = x * y
  def calcPerimeter(x: Int, y: Int): Int = 2*x + 2*y
}
