The cat shelter Happy Paw has a 5 feet by 4 feet large litter box filled with sand for the little felines to use. Last week, the cat shelter received a donation from a philanthropist named Patricia, which will be used to build a carpeted platform around the box that will catch the sand that gets stuck on the cats' paws. The organization Cat Shelters International has published guidelines on how to build a platform around a litter box. They recommend that the platform should have the same width on all sides and its total area should be half that of the box. Find the width of the carpeted platform.
