Q10 - Pythagoras & Perimeter

10 One of my Weasels is called Pythagoras (Yes that is another hint). I make him a racetrack that looks like this:
(imagine a 30cm x 15cm rectangle with a diagonal line across, then imagine I know how to put that image into this blog)
How long is the racetrack altogether (including the diagonal)? Answer to nearest centimetre.
(4 marks)
Perimeter of rectangle = 90cm.
Diagonal = 33.54.. Length = 124cm (nearest cm)
