The task is to find the length of the new fence EF which will cut the block of land exactly in half.

I can't attach any images for some reason. However the equations are: DC, 0.001x^6 - 0.051x5 + 0.87x4 - 5.33x3 + 5.529x2 + 11.781x + 312, DA, -308x + 312, AB, y = 17ln(x) + 4, BC is just a vertical linear line. Any help using the Trapezoidal Method or Simpson's rule would be greatly appreciated. I don't expect you to tell me how to do this question, I'm just asking for a point in the right direction, Thank you.
