Hi Sujal.

The challenge asks for: "The accepted parameter $size will be an array containing length and width in that order. Add a return value to the displayDimensions method that returns these values as a string "length x width".

Example: 12 x 14"

The first part says that the parameter $size that is being passed in is an array, therefore there is no need to initialize it as an array in your function. It's already coming in as one. The second part of that says the array contains length and width in that order meaning that $size[0] is the length, and $size[1] is the width.

Lastly it wants you to return a string that is 'length x width' so you'll need to use concatenation to accomplish this.

Have a look at this code:

<?php

class Render {

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

}

?>
