Commented by mr W last updated on 22/Apr/22

seems wrong!  PB=PD=3  AB=AP+PB=9+3=12  ((DB)/(DP))=((AB)/(DB))   ⇒DB=(√(DP×AB))=(√(3×12))=6  ⇒ impossible!

$${seems}\:{wrong}! \\ $$$${PB}={PD}=\mathrm{3} \\ $$$${AB}={AP}+{PB}=\mathrm{9}+\mathrm{3}=\mathrm{12} \\ $$$$\frac{{DB}}{{DP}}=\frac{{AB}}{{DB}}\: \\ $$$$\Rightarrow{DB}=\sqrt{{DP}×{AB}}=\sqrt{\mathrm{3}×\mathrm{12}}=\mathrm{6} \\ $$$$\Rightarrow\:{impossible}! \\ $$
