  Possible sides of $\triangle B$:
  $\textcolor{w h i t e}{\text{XXX}} \left\{5 , 3 \frac{3}{4} , 5 \frac{5}{8}\right\}$ or
  $\textcolor{w h i t e}{\text{XXX}} \left\{6 \frac{2}{3} , 5 , 7 \frac{1}{2}\right\}$ or
  $\textcolor{w h i t e}{\text{XXX}} \left\{4 \frac{4}{9} , 3 \frac{1}{3} , 5\right\}$
  
  #### Explanation:
  
  Suppose the sides of $\triangle A$ are
  $\textcolor{w h i t e}{\text{XXX}} {P}_{A} = 48 , {Q}_{A} = 36 , \mathmr{and} {R}_{A} = 54$
  with corresponding sides of $\triangle B$:
  $\textcolor{w h i t e}{\text{XXX}} {P}_{B} , {Q}_{B} , \mathmr{and} {R}_{B}$
