# Functions with two parameters

#1

// Write your function starting on line 3

var perimeterBox = function(3, 9) {
return 3 + 3 + 9 + 9;
}

What am I doing wrong?

#2

First of all read the instructions

1. Write a function called perimeterBox that returns the perimeter of a rectangle.
2. It should have two parameters.
3. One formula for perimeter is length + length + width + width;
4. Call the function and pass in any value for length and width you like.

``````// Write your function starting on line 3

var perimeterBox = function(1, 1) {
return 3 * 5;
}``````

Where is the Formular for a Perimeter?
Where do you call your function?
Why do you try to give paramter with name "1" and "1" better would be lenght and width

#3

I did as you said, but an error

#4

``````var add = function(a, b) {
return a + b;
}

Return is 3

I could give you the right Syntax but than you didnt learn anything.

#5

Here is my code, and it is correct:

// Write your function starting on line 3

var perimeterBox = function(a, b) {
return a + a + b + b;
}
perimeterBox(2, 3);

Thank you!
I thought I needed a number or string
