At Quiz Master Shop Towers we have some decking that is five metres wide. At one end it is three metres deep and the other end it is two metres deep, making an irregular trapezium.
There is a wall along the five metre and three metre sides.
A friend sometimes brings their dog and we sit with a drink putting the world to rights.
However, we are a bit concerned about the dog falling off the decking. What is the longest piece of rope that we can use to tie the dog so it can just reach the edge, but not fall off?
