ABCD is a rectangle. The points P, Q lie inside it with PQ parallel to AB. Points X, Y lie on AB (in the order A, X, Y, B) and W, Z on CD (in the order D, W, Z, C). The four parts AXPWD, XPQY, BYQZC, WPQZ have equal area. If BC = 19, PQ = 87, XY = YB + BC + CZ = WZ = WD + DA + AX, then the length of AB is 1) 241 2) 163 3) 217 4) 193
