Day 1: Arithmetic Operators Solution

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.
