Hacker rank Problem Link: https://www.hackerrank.com/challenges/js10-arithmetic-operators/problem?isFullScreen=true
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:
getArea(length, width): Calculate and return the area of a rectangle having sides Length and widthgetPerimeter(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
Constraints
- 1 <= Lengt, 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
Length * width = 3 * 4.5 = 13.5
The perimeter of the rectangle is
2. (Length + width) - 2 (3 * 4.5) = 15
