A 100 m. steel tape standardized at 20°C had a length of 100.600 m. It was used to measure a line A to B on tance was 622.70 m. The temperature at the time of measurement being 29° C. The stadia distance for the stme line was only 560.00 meters. Upon investigations the discrepancy was found out to be due to the fact that a 10 meter length (bet- ween 75-m. and 85-m.) was cut off. a) What is the true length of the sloping line? b) What is the horizontal distance of the same line if the difference of elevation between A and B is 0.72 meters?
