A microscope shows you an image of an object that is 140 tim

A microscope shows you an image of an object that is 140 times the object’s actual size. So the scale factor of the enlargement is 140. An insect has a body length of 6 millimeters. What is the body length of the insect under the microscope?

A. 840 centimeters

B. 8,400 millimeters

C. 84 millimeters

D. 840 millimeters

Solution

Given that

the scale factor of the enlargement is 140

let m is scalling factor hence m = 140

now if an insect has a body length of 6 millimeters

then it show

he body length of the insect under the microscope = scale factor x size of the insect

= 140 x 6 = 840 millimeters

Option : D. 840 millimeters is correct
