Question

quadrilateral abcd is the image of quadrilateral abcd under a dilation with a scale factor of $\frac{1}{3}$. what is the length of segment $overline{cd}$? units

Explanation:

Step1: Identify C' and D' coordinates

Assume grid units: C'(5,5), D'(5,8)

Step2: Calculate C'D' length

Vertical distance: \(8 - 5 = 3\) units

Step3: Find CD using scale factor

CD = C'D' / (1/3) = \(3 \times 3 = 9\)

Answer:

9
