PHP-OOP - Getter from static class help

Question

Hi
I´m learning PHP OOP and i´m stuck.
The problem is that I need to do this:
Challenge Task 4 of 4
The accepted parameter $room will be an object which has a method named getDimensions. Add a return value to the detailsKitchen method that displays "Kitchen Dimensions: length x width", where length x width is returned from the displayDimensions method.
You will need to call the static method displayDimensions from within the Render class and pass the dimensions from the $room object using the getDimensions method
Final Output Example: Kitchen Dimensions: 12 x 14
My code is:
<?php class Render {
  public static function displayDimensions($size)
  {
    $word0 = $size[0];
    $word1 = $size[1];    
    return $word0 . " x " . $word1;
  }
   public function getDimensions (){
    $room = "Kitchen Dimensions: ";
    $room .= $self->word0;
    $room .= " x ";
    $room .= $self->word1;
  }  
   public static function detailsKitchen ($room){
    return $room;
  }
}
?>
THE ERROR CODE SAYS IT can't convert $Room to a string.....
Thanks :-)

Hi, @glen rose (https://teamtreehouse.com/glenrose),
You don't need to create the getDimensions method. What they meant is that the $room parameter already is an object and this  object already has the getDimensions method. So you would use it like this within the detailsKitchen method $room->getDimensions().
In the detailsKitchen method you just need to return "Kitchen Dimensions: length x width". Remember that the displayDimensions method is already like  length x width, so you do: return "Kitchen Dimensions: " . self::displayDimensions() ;
It's still not going to work, because the displayDimensions method accepted a parameter, which are the exactly  numbers for the length and width. You get these numbers through $room->getDimensions(). So you add that as a parameter. Have a look at my code.
php
class Render {
    public static function displayDimensions ($size) 
    {
        return "$size[0] x $size[1]";
    }
    public static function detailsKitchen ($room)
    {
        return "Kitchen Dimensions: " . self::displayDimensions($room->getDimensions()) ;
    }
}

Ahhhhh  now I see....   
I think it gets hard to follow using an object in the parameter displayDimensions.....
But I get it now.  
 Thanks for the help :-)    !!!
