$ABCD$ একটি সামান্তরিক যার কর্ণদ্বয়ের ছেদবিন্দু $O$। $AO ও BC$ এর মধ্যবিন্দু যথাক্রমে $P ও Q$. $\angle A =\angle DPQ$ এবং $\angle DBA =\angle DQP$। $AB$ এর দৈর্ঘ্য $1$ একক হলে, $ABCD$ এর ক্ষেত্রফল কত?
$ABCD$ is a parallelogram and it's diagonals meet at point $O$. $P$ and $Q$ are the midpoints of $AO$ and $BC$ consecutively. $\angle A $ =$\angle DPQ$ and $\angle DBA$ =$\angle DQP$. If $AB$ = $1$ unit, then find out the area of $ABCD$.

We cannot solve our problems with the same thinking we used when we create them.

Re: Dhaka Junior 2015/9
this problem is already discussed in viewtopic.php?f=8&p=17163#p17163.Just a difference : $AB = 2$ instead of $1$.
