Since both drawings are similar and have a scale factor, we can say that all sides keep the same scamle factor, if the scale drawing is in a proportion of 3:1 means that all of its sides is 3 times the real objects sides.

write this as equations


\begin{gathered} 3\cdot a=21in \\ 3\cdot b=18in \end{gathered}

to find the respetive values for a and b we divide the sides by 3


\begin{gathered} a=(21in)/(3)=7in \\ b=(18in)/(3)=6in \end{gathered}

The correct answer is D.
