Final answer:
The question relates to the impact of temperature on the measurement of a plot of land with a steel tape measure and how this affects the total price. It requires mathematics to solve, but also integrates physical concepts like thermal expansion, without specific values to provide a precise answer.
Step-by-step explanation:
The question at hand deals with how the total price of a plot of land in Hong Kong would change if the land was measured with a steel tape measure on an unusually warm day, with temperatures 20°C above normal. This scenario highlights the effects of thermal expansion on measurement tools, which is a concept in physics. However, the application of calculating the potential change in cost due to discrepancies in land measurement is a mathematical problem.
Commonly, steel expands with heat and contracts with cold at predictable rates, and precise measurements require temperature corrections. Unfortunately, without the specific coefficient of thermal expansion for the tape, or the original normal measurement temperature, we cannot determine the actual length change. Normally, this physics concept would be applied to calculate the length change and subsequently, the area change, after which we would multiply by the land cost per square meter to find the difference in total price. Without these specifics though, we cannot provide a numerical answer.
