A rectangular garage door has a width of (3d+6) and a height of (6d-2). A second rectangular garage door is drawn with a width that is tripled and a height that is doubled. Find the difference between the area of the original garage door and the area of the new garage door. (area = width x height. Find original area, new area and the difference.)
