Numerical Example For Error Due To Wrong Measuring Scale
A surveyor measured the distance between two points marked on the plan drawn to a scale of 1cm = lm (R.F. = 1: 100) and found it to be 60m. Later he detected that he used a wrong scale of 1 cm = 50 cm (R.F. = 1: 50) for the measurement.
(a) Determine the correct length.
(b) What would be the correct area if the measured area is 70 m²?
