Question

A dilation with a scale factor of 2 is applied to the image below. What is the length of the new image?

Answer 1

The length of the new image is 3 cm

Explanation:

we know that

To find the length of the new image, multiply the length of the original image by the scale factor

Let

A'B'-----> the length of the new image

z ----> the scale factor

we have that

AB=1.5 cm

z=2

A'B'=z*AB

A'B'=2*1.5=3 cm
