# Day 1: Arithmetic Operators | 10 Days of JavaScript – Hacker Rank Solution

Day 1: Arithmetic Operators | 10 Days of JavaScript – Hacker Rank Solution: Hey Guy’s In this post we are solving Day 1: Arithmetic Operators – HackerRank Solution which is a part of 10 Days of JavaScript Series.

## Objective

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

Complete the following functions in the editor below:

1. 1. `getArea(length, width)`: Calculate and return the area of a rectangle having sides length and width.
2. 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 <= lengthwidth <= 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

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.
