When I took Chem the teacher was makpid on using the correct units... otherwise they wouldn't cancel out or something like that.
It's different when you are doing an equation and when you are writing a final answer. Also, in a math/chem problem you have to figure out what the measurement is, so it is important to write it (unless it is obvious from the question what measurement you are answering). Either way this is not a chem class.

and would the teacher mark the either answer (2 or 2 feet) wrong? in the science class???
I got it wrong for not writing feet. She didn't mark it wrong, just marked -1 which is the total credit for the question.

I have been marked off a point or two for not including the correct unit. It can be very important if it's a conversion problem (say, kilometers per hour to meters per second) to keep track of which units you're using, especially if it's a complex conversion requiring a number of steps.
This is as simple a conversion as simple conversions get, and measurement of the answer was clearly stated in the question, hence my thinking that answering "2 feet" would be like saying "2 feet feet".
