A 30-m steel tape at 20°C is used to measure a rectangle whose sides were recorded as 144.95m and 113.00m. The average temperature during the measurement is 30°C with a standard pull and applied pull of 55N. Use the coefficient of expansion of steel tape as 0.0000116/°C. a) Compute the actual length of the tape during measurement. Compute the true length of each side of the rectangle. c) Compute the true area. b)
