17. Trapezoid ABCD has AB || CD, BC = Let O be the intersection of the diagonals AC and BD, and let P be the midpoint of BD. Given that OP = 11, the length AD can be written in the form m /n, where m and n are positive integers and n is not divisible by the square of any prime. What is m +n ? CD = 43, and AD I BD. %3D (A) 65 (В) 132 (С) 157 (D) 194 (E) 215
