A castle is surrounded by a rectangular moat, which is of uniform width of 12 feet. A corner is shown in the top view at right. The problem is to get across the moat to the dry land on the other side, without being able to use the drawbridge. All you have to work with are two rectangular planks, whose lengths are 11 feet and 11 feet, 9 inches. Find a way to get across.
