Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

In order to find the answer, we need to do as follows:

Step-by-step explanation:

Given

See attachment for QRST and Q'R'S'T

Required

The dilation rule

First, we calculate the scale factor (k)

From the attachment, we have:

QR = 4

Q'R' = 8

k, is then calculated as:

k = \frac{Q'R'}{QR}

k = \frac{8}{4}

k =2

<em>Hence, QRST is dilated by a factor of 2</em>
