To determine the scale factor from EDGF to QRST:
[tex]\begin{gathered} \text{EDGF = }35\text{ } \\ \text{QRST = 42} \end{gathered}[/tex]
The Quadrilateral QRST is similar to quadrilateral EDGF with a scale factor:
[tex]\frac{\text{QRST}}{\text{EDGF}}=\frac{42}{35}[/tex]
The scale factor =
[tex]\frac{\text{QRST}}{\text{EDGF}}=\frac{42}{35}=\frac{6}{5}[/tex]
Therefore the scale factor from EDGF to QRST = 6/5
Hence the correct answer is Option D
