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 input: String = readLine()
    val list: Array[String] = input.split(" ")
    val a: Int = list(0).toInt
    val b: Int = list(1).toInt
    
    val area: Int = a * b
    val perimeter: Int = (a + b) * 2
    println(area + " " + perimeter)
  }  
  //def readLine(): String = {"3 5"}
}
