Explanation / Answer

1/f) = (1/p) + (1/q)
(1/32.1) = (1/35.4) + (1/q)
(1/q) = 2.904*10^-3mm
q = 344.35mm = 0.34435m

(b)on the right of lens  if the image is on the far side of the lens as the object, the imagedistance is positive and the image is real.
h'/h = -(q/p)
h'/2.59cm = -(34.435cm/2.59cm) = -13.295
h' = 2.59 * -13.295 = -34.434cm
