Please add more tests, otherwise the problem is trivially solvable.

The solution isn't unique - it could be anything between 0 and 12.5. Need to specify that only integer side lengths are allowed (even then there could be multiple solutions). Also more test cases are required.

It is'nt always true! E.e. whether a quadrat's diagonal is 5 it's sides are 5/sqrt(2)! And the area will be 12.5!!
