Explanation / Answer

given that object height = h0= 2.30cm object distance d0= 36.6mm = 36.6* 10-3m= 0.0366m focal length = f = 35.9mm = 0.0359m    from the lens eq    1/di = 1/f - 1/d0          = 1/0.0359m -1/0.0366m    di= 1.89m image is rigth of lens because it is positive m= - di/d0      = - 189cm/0.366cm = -516.3 image hight = hi = mh0 plug in values hi = ------cm plug in values hi = ------cm
