200 yuan. For an 80-square-meter property, the property fee is paid according to 2.5 yuan per square meter, the property area is A square meter, and the unit price of the property fee is B yuan per square meter.

The calculation result is that the total property fee is equal to 200 yuan. Therefore, the 80-square-meter property is subject to the 2.5 yuan property fee per square meter, and the 200 yuan property fee is always required.
