# 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.
