Answer: 
Step-by-step explanation:
 You need to analize all the information given in the exercise.
 You know that the actual height of the T-rex on the projector lens is the following: 
 
 The height of the projected T-rex is:
 
 Make the conversion from meters to centimeters:
 
 Therefore, the scale factor will be:
 
 Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:
