The tap was manufactured at a room temperature of 25 degree centigrade. But in the field where this tap is utilized for measuring horizontal distance was 30 degree centigrade mean temperature, and the measured distance between two points was 200m. What is the absolute length of distance between two points? Assume the coefficient of thermal expansion of tap material is 10x10^-6 per degree centigrade
