In a square $\displaystyle ABCD$ of side $\displaystyle 6$ units $\displaystyle P, Q$ are mid points of $\displaystyle BC, CD$ respectively.
The line segments $\displaystyle BQ, DP$intersect in $\displaystyle R$ then find the area of the quadrilateral $\displaystyle ABRD$
$\displaystyle R$ is the centroid of triangle $\displaystyle BCD$
