Day 1: Arithmetic Operators JavaScript – Hacker Rank Solution

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. 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

Data TypeParameterDescription
NumberlengthA number denoting the length of a rectangle.
NumberheightA number denoting the height of a rectangle.

getArea

Data TypeParameterDescription
NumberlengthA number denoting the length of a rectangle.
NumberheightA number denoting the height of a rectangle.

getPerimeter(length, height)

Constraints

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

Output Format

FunctionReturn TypeDescription
getAreaNumberThe area of a rectangle having sides length and width.
getPerimeterNumberThe perimeter of a rectangle having sides length and width.

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.
