1 is as good a value as any. The lengths are totally irrelevant, so assuming 1 for an example case just simplifies the maths.
As for it being a geometry problem - maybe so, but I solved it my way and found the answer - feel free to post a shorter solution if you know it. Personally I feel no need to look for one now as I've already solved the problem.
