Seems that I got the wording right.
That is correct

@venda saidIf it were inside, the question wouldn't be answerable. (Consider a fort 10m wide and 70m long...)
A fort is a convex polygon 700m in perimeter.Patrols walk around the fort staying exactly 10m from it's walls.How far does the patrol walk in one circuit ?
Good luck.I don't even know what a convex polygon is!
My first question would be are they walking inside or outside,but as the question doesn't say,I suspect it doesn't matter!
@venda saidDraw it. Start by looking up what a convex polygon is, draw some (start with a rectangle, it's easiest to think about), then draw how you would walk a fixed distance around it. It's easier to see than to talk about.
The paper doesn't give a numerical answer but there is an explanation:-

Way beyond me I'm afraid.
@venda saidI can do it in...
A chess variant is played on a large board but the knights L shaped move is 7 squares in one direction and 10 in another.If I want to move a knight one square horizontally,what are the fewest moves that I must make ?

@venda saidThe worst point for any system of direct links is the one that is just shy of 350, halfway between the direct links.
A railway system has 700 stations connected in a circle so that sometimes travellers have to call at 350 stations.New high speed services are proposed by the government that directly links stations 25 places apart,reducing the number of stations that have to be visited.The opposition argues that stations 28 apart should be linked instead.
Which proposal leads to the fewest visits in the worst case

I asked lots of people what their favourite season is:
16 didn't choose summer,14 didn't choose Autumn,15 didn't choose winter and 12 didn't choose spring.
How many people did I ask ?
