    are you sure you set up the integral right?

    L = \int_{-8}^{216} \sqrt{1 + [x']^2}~dy

    How did you set up the integral?

    How do you know your answer is way off?

    Letting us know what you have done so far would be far better than just telling you the answer.

    Unless I am missing something here, this integral can only be solved numerically....
