As the scale factor is 4:1 it means that for each 4inches in scale drawing correspond to 1 inch in the object.

Then, to find the side lengths in the object you multiply the measure of each side in the scale drawing by 1/4:


\begin{gathered} 10in\cdot(1)/(4)=2.5in \\ \\ 10in\cdot(1)/(4)=2.5in \\ \\ 12in\cdot(1)/(4)=3in \end{gathered}Then, side a is 2.5 inches, side b is 2.5in and side c is 3inches
