A map is drawn to a scale of \(1:25\,000\).
This scale can be expressed as 1 centimetre represents \(n\) kilometres. Find \(n\).[1]
The distance between two points on the map is 41.5 centimetres. Find the actual distance, in kilometres, between the two points.[1]
A farm has an area of \(51.2\) square centimetres on this map. Find the area of the farm, in square centimetres, on a second map which is drawn to a scale of \(1:80\,000\).[2]
