Scale drawings and map scales (1 cm represents…, 1 : n)Exam-style questions

Turn a length on a map or scale drawing into a real length and back again: use a scale written as "1 cm represents 5 km", as a scale bar or as a ratio 1 : n, change the units inside a ratio scale, write any scale in the form 1 : n, follow a route instead of a straight line, measure and draw to scale, and scale an area by the square of the scale.
