What did I do wrong here?

I know that this is not correct but I took a stab at it anyway. Can someone offer a little guidance?


class Render {
  public static function displayDimensions($size)
    $size[] = array("length","width");
    $size = 'length'*'width';
    return $size;

To return the string "length x width" where the length and width are inside the array $size, you can use the indexes of the array to access those values.

Indexes for arrays start at 0 so your code will look like this inside the function.

return $size[0] . " x " . $size[1];

Hope that helps!
