Return the $size array as a string?

I don't understand what they want me to do. I tried it with return $size, but that returns the array itself. So i made a foreach loop and append it to a var named $output.. and then return $output.

index.php 
<?php

class Render {
    public static function displayDimensions($size){
      return $size;
    }
}

?>

The task is looking for the string "length x width". For this you can specify the individual elements concatenated with x as

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

Who the heck makes such things separate? If you have a dimension, you prob make it something like ['10cm x 20cm','5cm x 10cm']. If you make it something like ['10cm','50cm','14cm'] those are not dimensions, just random values inside an array. I was expecting something like ['10cm x 20cm']... Either they fix these arrays or they show how the array looks like.
