I have no idea what i should do here.

Hello, i guess that this is my worst lesson i ever had. I feel like i forgot what speaking and reading is. For an excuse, english isn't my native language so i might not understand it, for some reason... i doubt it tho.

So, $room object has a getDimensions method, ok. Add a return value to the detailsKitchen. return "Kitchen Dimensions: ".somethinghere; , ok. length x width is returned from displayDimensions.

return "Kitchen Dimensions: ".self::displayDimensions(); The displayDimensions has already an array with dimensions.

Call displayDimensions inside the Render class, ok.

Now even tho there is an array from the last step i need to get the dimensions from the $room object. So it would be $room->getDimensions right?

But what the heck is getDimensions returning? Json object, string, array with two integers? $room and getDimensions is just a black box that i don't see so i have no idea what they return. A snippet would be all i need.

<?php

class Render {
    public static function displayDimensions($size)
    {
         return $size[0].' x '.$size[1];
    }

    public static function detailsKitchen($room)
    {
        return "Kitchen Dimensions: ".self::displayDimensions();
    }

  $this->display
}
?>
