Plane Scale
Question: On a map of a state, 1cm represents 5 km. Construct a plain scale capable of measuring the distance between two cities 100 km far from each other. Calculate R.F. & show the distance of 73 km on the scale.
Solution:
- R.F. = 1/500000
- Max Length(M.L.) = 100 km
- Length of Scale(L.O.S.) = 1/500000 × 100 × 100000 = 20 cm
