I cant figure this one out. Can I get the code please.

return $size->length . "x" . $size->width;

Why wont this code work?

index.php 
<?php

class Render {
    public static function displayDimensions($size)
    {
        return $size->length . "x" . $size->width;
    }
}

?>

It's because it's an array without a named key value pair. So you want the array at index of 0 times the array at index of 1.

<?php

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

?>

Hope this helps! :sparkles:
