A castle is surrounded by a rectangular moat, which is of a uniform width of 12 feet. The problem is to get across the moat to dry land on the other side without using the drawbridge. To work with, you have only two rectangular planks, whose lengths are 11 feet and 11 feet, 9 inches respectively. Show how the planks can get you across.
Can you prop them up like a tent?
Or if you want you can lay one across a corner...then place the other on it to the other side.....(to get to the castle)
