Day1 Arithmetic Operators

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 <= 100
• length and height are scaled to at most three decimal places.

Output Format

Sample Input 0

1
2

3
4.5

Sample Output 0

1
2

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 + height) = 2 X (3 + 4.5) = 15.

function getArea(length, width) {
    let area;
    area = length * width;

    return area;
}

function getPerimeter(length, width) {
    let perimeter;
    perimeter = 2 * (length + width);
    
    return perimeter;
}
