Hello Samsor Ithnin,

Let's get to the question Task 2 of 4. 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. It seems in your code you are expecting variable $size to be an object. task asks for an array.

<?
    return $size[0] . " x " . $size[1];
?>
