IN REDUCING ANY MAP TO GIVEN SIZE, THE FOLLOWING STEPS SHOULD BE FOLLOWED:
Measure the length and width of the map. Divide the length and width by 2 or 4 if you are asked to reduced the map to half or a fourth of its original size. For example, if the length and width of a map are 24cm and 20cm respectively, such a map should measure 12cm by 10cm if seduced to half its size and 6cm by 5cm if reduced to a fourth of its size and so on.Having reduced the original map, it is obvious that the scale would equally change. Therefore, if a map has a scale of 1:50,000, the scale of the map changes to 1:100,000 if the size has been reduced to half, and 1:200,000 if the size of the map has been reduced to a fourth of its original size.The features to be shown on the reduced map should also be proportional to the required size of the map.When you have finished drawing the reduced map, remember to write its title and the new horizontal scale.
