Question

Square A is a dilation of Square B. What is the scale factor of the dilation? Write the answer as a simplified fraction.

Answer 1

$\begin{gathered} l_A=kl_B,\text{ l\_A is the lenght of the square A, and l\_B is the lenght of the square B},\text{ k is the scale factor} \\ \\ \frac{l_A}{l_B}=k \\ \\ k=\frac{35}{28} \\ \\ k=\frac{5}{4}=1.25 \\ \\ \\ \text{ the }scale\text{ factor is 1.25} \end{gathered}$
