Task

Write two function for the following instructions:

  1. getArea(length, width): Calculate and return the area of a rectangle having sides length and width.
  2. getPerimeter(length, width): Calculate and return the perimeter of a rectangle having sides length and width.

The values returned by these functions are printed to stdout by locked stub code in the editor.

Constraints

  • 1 ≤ length, width ≤ 1000
  • length and width are scaled to at most three decimal places.

Input Format

getArea(length, width):

Data Type Parameter Description
Number length A number denoting the length of rectangle.
Number width A number denoting the width of rectangle.

getPerimeter(length, width):

Data Type Parameter Description
Number length A number denoting the length of rectangle.
Number width A number denoting the width of rectangle.

Output Format

Function Return Type Description
getArea(length, width) Number The area of a rectangle having sides length and width.
getPerimeter(length, width) Number The perimeter of a rectangle having sides length and width.

Sample

Input 

3
4.5

Output 

13.5
15

Explanation

  1. The area of the rectangle is length x width = 3 x 4.5 = 13.5.
  2. The perimeter of the rectangle is 2 x (length + width) = 2 x (3 + 4.5) = 15.
