Question

the trapezoid ( klmn ) is a dilation of the trapezoid ( klmn ). what is the scale factor of the dilation?
simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.

Explanation:

Step1: Get length of MN

MN is from (-6,9) to (4,9), length = 4 - (-6) = 10

Step2: Get length of M'N'

M'N' is from (-1,3) to (2,3), length = 2 - (-1) = 3

Step3: Calculate scale factor

Scale factor = M'N' / MN = $\frac{3}{10}$

Answer:

$\frac{3}{10}$
