Error in Temperature and Area | sample problem | elementary surveying

This video solves a sample problem on error correction due to temperature and error correction in area. Sample problem: A rectangle is measured using a 30-m steel tape which is 2-mm too long at 20 degrees Celcius with a pull of 55 N. The sides are recorded as 144.95 m and 113.00 m. The average temperature during the measurement is 30 degrees Celsius with a pull of 55 N. Use coefficient of expansion of steel tape as 0.0000116 m/C. a. Compute the actual length of tape during measurement. b. What is the true area? c. What is the error in area in sqm?
