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 extends App {
  val scanner = new java.util.Scanner(System.in)
  val a = scanner.nextInt
  val b = scanner.nextInt

  val area = a * b
  val perimeter = 2 * a + 2 * b

  println(s"$area $perimeter")
}
