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 Ruby (judge verdict: Accepted)

def rectangleArea(x,y)
  return x * y
end

def rectangleLength(x,y)
  return (x + y) * 2
end

s = gets.chomp
x = s.split(" ")[0].to_i
y = s.split(" ")[1].to_i

puts rectangleArea(x,y).to_s + ' ' + rectangleLength(x,y).to_s
