Question

Quadrilateral QRST is similar to quadrilateral EDGF. What's the scale factor from EDGF to QRST?Question options:A) 6∕7B) 5∕4C) 5∕6D) 6∕5

Answer 1

To determine the scale factor from EDGF to QRST:

$\begin{gathered} \text{EDGF = }35\text{ } \\ \text{QRST = 42} \end{gathered}$

The Quadrilateral QRST is similar to quadrilateral EDGF with a scale factor:

$\frac{\text{QRST}}{\text{EDGF}}=\frac{42}{35}$

The scale factor =

$\frac{\text{QRST}}{\text{EDGF}}=\frac{42}{35}=\frac{6}{5}$

Therefore the scale factor from EDGF to QRST = 6/5

Hence the correct answer is Option D
