in $ABDC$ quadrangle, diagonal $AB$ bisects $\angle CBD$ $DB$ and $DA$ touches the circumcentre of $ABC$ at $A$ and $B$. if the circumcentre of $ABC$ is $20$ and $ABD$ is $12$. find $BD$
\[\sum_{k=0}^{n-1}e^{\frac{2 \pi i k}{n}}=0\]

আচ্ছা,বাংলায় কপি করতিছি ।
$ADBC$ চতুর্ভুজে $AB$ কর্ণ $\angle CBD$ কোণকে সমদিখন্দিত করে । $DB$ এবং $DA$ বাহুদ্বয় $ABC$ ত্রিভুজের পরিবৃত্তকে $A$ এবং $B$ বিন্দুতে স্পর্শ করে । $ABC$ ও $ABD$ ত্রিভুজের পরিসীমা যথাক্রমে $২০$ ও $১২$ । $BD$ এর দৈর্ঘ্য কত ?

You have written 'Circumcentre' instead of 'Perimeter' I think.
There is no integer solution for $BD$. I think the solution is.
