Show how the design could be done then.
Stage 2 & 3 Solve it...!
The Hungry Spider
A spider is
in the top corner (A) of a rectangular room, 10m long, 5m wide and 3m
high. The spider spots a tasty snack in the furthest corner of the room
What is the shortest distance the spider could travel along the edges
