Question

The length of AB is 5 units.

What is the length of the image of the line segment after a dilation with a scale factor of 5/2?

Answer 1

The length of the image after a dilation will be the original length times the scale factor.

The original length is 5 units.
The new length or the image is:
(5 units)(5/2)
= 25/2 units
= 12 1/2 units
= 12.5 units
