A microscope shows you an image of an object that is 20 times the objects actual size. Therefore, the scale factor of the enlargement is 20. An insect has a body length of 10 millimeters. What is the body length of the insect under the microscope?
We just have to multiply 20 by 10mm, which is 200mm. 100mm is equal to one centimeter, so the body length of the insect under the microscope is two centimeters.
