Rectangle QRST is dilated with the origin as the center of dilation to create rectangle Q'R'S'T'.

scoundrel [369]

Answer:

Rule: dilation about the origin by a scale factor of 2

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:

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

$k = \frac{8}{4}$

$k =2$

Hence, QRST is dilated by a factor of 2
