Approximate the arc length of the curve y=(1/4)x^4 over the interval [1,2] using the Trapezoidal Rule T8.

I was never taught how to use the Trapezoidal Rule, so I was surprised to find this problem in my most recent Calculus assignment. How would you solve a problem like this?

Thanks in advance to anyone who's willing to help out.

This is a WebWork problem for my Calculus 2 class and all the answers I got from online calculators weren't considered correct, which is why I'm asking for some help on here.
