Question

the length of (overline{ab}) is 9 centimeters. a dilation with a scale factor of 2 is applied to (overline{ab}). what is the length of the image of (overline{ab}) after the dilation is applied? enter your answer in the box. (square) cm

Explanation:

Step1: Recall dilation rule

Dilation scales length by scale factor. So new length = original length × scale factor.
Original length of $\overline{AB}$ is 9 cm, scale factor is 2.

Step2: Calculate new length

New length = $9\times2 = 18$ cm.

Answer:

18
