Solution
Scales can be represented in three methods are.
- Statement Scale:
The statement scale describes the relationship of map distance to the ground distance in words, such as one centimetre to ten kilometres. It is expressed as 1cm = 10 km. - The Representative Fraction (R.F)
- It describes the proportion or ratio of the map distance to ground distance. It is usually abbreviated as R.F. It is stated as 1/100000 or 1:100000
- This means that one unit on the map represents 100,000 of the same unit on the ground.
- This unit may be an inch or a centimetre or any other linear measurement unit.
Representative Fraction (R.F.) = `"Distance on the map"/"Distance on the Ground"`
- Linear (or) Graphical scale:
In geography, a linear scale is represented by a straight line divided into equal parts (Primary and secondary) to show what these markings represent on the actual ground. This scale helps in the direct measurement of distance on the map.
