The scale statement above is one type of statement that maps generally use to show the relashionship between distance in the real world to distances in the scale drawing.
Through measurement, we could check that the distance representing 100 km in the real world is represented by a distance of 1 cm in the scale drawing (map). Another way of representing this relationship is shown in the scale statement below.
Another method of expressing the scale statement would be by stating the ratio "Scale: 1 cm : 100 km"
