Triangle ABC is dilated to create triangle A'B'C' using point O as the center of dilation. What is the scale factor of the dilation? One-third 3 4 One-fourth

The scale factor is 4

Step-by-step explanation:

This question requires an attachment; I'll answer this question using the attached figure

From the attachment

Length OA = 3 units

Length OA' = 3 units + 9 units

Length OA' = 12 units

Scale Factor is calculated as follows;

Given that the original shape is ABC, the original side will be OA

Hence, Original Side = 3 units

New Side = OA' = 12 units

The formula becomes

Hence, the scale factor is 4

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
