From the graph the area of the polygon Q is 4.5 square units.
The area of polygon P is 72.
The ratio of area of polygon is equal to the square of scale factor. So,
![\begin{gathered} (4.5)/(72)=m^2 \\ m=\sqrt[]{(1)/(16)} \\ =(1)/(4) \\ =0.25 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/sxkroj5v22mrf2g1zi6s8nrm4ziovflm7o.png)
So scale factor Diego used to go from polygon P to Q is 0.25 or 1/4.
Answer: 1/4 or 0.25
