7. Distance of 180m was measured with a 50 ft chain. On standardization, the actual length of the chain was found to be 50.7 ft What is the true distance? (5 marks) 8. A 90-m tape was standardized and found to have an actual length of only 89.562 m (between the 0 and 90.000-m tape marks). What is the required correction per tape length? (5 marks) 9. It is necessary to lay out and mark a point D exactly 80.000 ft distant from point C for a certain construction project. A steel tape with a standardized length of 20.008 ft is used. What should be the distance measured with that tape from C to accurately set the mark for point D? (5 marks) 10. A surveying student walked along with a ground where rough distance measured 300-ft line on the level ground five times and counted 122, 121, 102, 123, and 121.5 paces
