प्रश्न
Describe the method by which the distance on a curved line is measured.
उत्तर
The distance on a curved line is measured using a piece of twine or a divider.
In the divider method, a divider whose pointed ends are 1 or 2 cm apart is used. Beginning at one end of the feature to be measured, the divider is turned continuously till the other end is reached. The number of turns are counted and then using the scale of the map, the actual distance on the ground calculated.
In the twine method, a twine is placed along the feature to be measured from one end to another. The length of the twine is then measured in cm or inches using a ruler or linear scale and then converted into km or miles using the scale of the given map.
