Quizplus · Accepted Answer

The scale factor for the map to real-life conversion is found by dividing the real-life distance by the map distance for the shortest side, which is 129 km / 9 cm = 14.33 km/cm. Applying this scale factor to the longest side of the map, 14 cm, gives 14 cm * 14.33 km/cm = 200.62 km, which rounds to 201 km.
