The area of quadrilateral $ABCD$ is $84$. The diagonals intersect at point $P$. If
$$|AP|= 5,quad|BP|= 3,quad|CP|= 7,quad|DP|= 2, $$
calculate the area of the four triangles in quadrilateral $ABCD$.

Hint: draw the perpendicular from $A$ onto the $BD$ diagonal. What's the ratio of the areas for triangles $ABP$ and $APD$? Repeat the procedure and write all areas in term of the area of $ABP$. Sum them together and you find the area of $ABCD$.
