Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor =
Since, S is being dilated with a scale factor to form T,
So, the figure S is the preimage and figure T will be the image,
Length of one side of image T = 8
Length of one side of preimage = 2
Therefore, Scale factor =
= 4
Scale factor by which figure S has been dilated to form figure T is 4.
