Final answer:
Using stride length to measure distances when selling land can lead to inaccurate and inconsistent measurements due to variations in stride length and lack of standardized units.
Step-by-step explanation:
If the length of a person's stride were used to measure distances, there could be several problems when trying to sell a piece of land. Stride length can vary from person to person and can also be affected by factors such as fatigue or the terrain. This would make it difficult to obtain accurate and consistent measurements of the land using strides. Additionally, the units of measurement would not be standardized, as different people may have different stride lengths or use different measurements for their stride. This would introduce ambiguity and inconsistency when measuring and describing the land.
