Question: The marina beach at Chennai is 2.5 km long, on the inspection of the road map its equivalent distance measures 5 cm. draw a diagonal scale to read 50 m minimum. Mark on the scale a distance of 6350 m.

Solution:

• R.F. = 5/250000 = 2/100000
• Max Length (M.L.) = 50 meters
• Length of  Scale (L.O.S.) = 700000 × 2/100000 = 14cm
