Day 1: Arithmetic operators 10 days of javascript hackerRank solutions

In this Day 1: Arithmetic operators 10 days of javascript hackerRank solutions you need to Complete the getArea(length, width) function that Calculate and return the area of a rectangle having sides length and width. and a getPerimeter(length, width) function that Calculates and returns the perimeter of a rectangle having sides length and width.

Objective

In this challenge, we practice using arithmetic operators. Check out the attached tutorial for resources.

Task

Complete the following functions in the editor below:

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.

Input Format

getArea

getPerimeter(length, height)

Constraints

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

Output Format

Sample Input 0

3
4.5

Sample Output 0

13.5
15

Explanation 0

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