## 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.
`getArea(length, width)`

: Calculate and return the*area*of a rectangle having sidesand**length**.**width** - 2.
`getPerimeter(length, width)`

: Calculate and return the*perimeter*of a rectangle having sidesand**length**.**width**

The values returned by these functions are printed to stdout by locked stub code in the editor.

**Input Format**

Data Type | Parameter | Description |
---|---|---|

Number | length | A number denoting the length of a rectangle. |

Number | height | A number denoting the height of a rectangle. |

**getArea**

Data Type | Parameter | Description |
---|---|---|

Number | length | A number denoting the length of a rectangle. |

Number | height | A number denoting the height of a rectangle. |

**getPerimeter(length, height)**

**Constraints**

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

**Output Format**

Function | Return Type | Description |
---|---|---|

getArea | Number | The area of a rectangle having sides andlength. width |

getPerimeter | Number | The perimeter of a rectangle having sides andlength. 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## Day 1: Arithmetic Operators | 10 Days of JavaScript – Hacker Rank Solution
