These instructions are kind of confusing. Can someone help clarify the ask here?

Question

detailsRoom should accept a single object parameter named $room. The $room object will have the follow methods:
getName: will return a string
getDimensions: will return and array of size integers
Add a return value to the detailsRoom method that displays "name Dimensions: length x width", where name is returned from the room getName method and length x width is returned from the render displayDimensions method.
You will need to call the static method displayDimensions from within the Render class and pass the dimensions from the $room object using the getDimensions method
Final Output Example: Kitchen Dimensions: 12 x 14
Am I supposed to be making the getName and getDimensions methods? Do I need to be making a room class? It's worded kind of funky, and I'm having a really hard time deciphering the ask here.
```index.php
<?php class Render {
  public function getDimensions()
  {
    return $self->displayDimensions;
  }
  public function getName()
  {
  }
  public static function displayDimensions($size)
  {
    $output = implode(" x ", $size);
    return $output;
  }
}
?>
```

Hi there, @Chris Hummel (https://teamtreehouse.com/chrishummel) ! This part of the challenge is trying to tell you that somewhere there is another class file that you can't see that makes a Room. The $room is an instance of that class and will be sent in as a parameter. It's only asking you to make the detailsRoom method. 
The Room class which exists elsewhere has a method called getName() and getDimensions. You will use the getName() which returns a string like "Kitchen" and the getDimensions() which returns an array like [14, 12] where the numbers are the length and the width. You're going to need that so that you can send in that array to the displayDimensions method as the $size.
```php
public static function detailsRoom($room) {
     return $room->getName() . " Dimensions: " . self::displayDimensions($room->getDimensions());
}
```
First we use the getName method on the Room object that was passed in. Then we do a bit of concatenation for the  " Dimensions: " part, and one more concatenation. This time, we're calling the displayDimensions which is a method in the same class and because it's static, you will need to use self:: here. Then we pass in the dimensions that were returned from the Room object's getDimensions, which should be an array with two numbers.
Hope this helps! :sparkles:

Just a note, there's a typo in the question on the test. 
"The $room object will have the follow methods:"
 should be "following"
