@psetter, you have to give precision for answer with cases like "5 7", perimeter is 17, and area approx 12,49749975.
What is the judge ? I hope it's "Ignore FP rounding do 10^-2".
Please fix description for that or the problem will be hidden.
Moreover, please give maxscore possible.
I hope "12.0" is an accepted answer for "12" !
