D.

Plotting the figure roughly on a graph we can conclude that PQRS is a parallelogram.

Hence area of parallelogram = b *d

Here b = 9 and d = 3

Hence area = 27

On plotting the points on the x-y coordinate, we see that it forms a parallelogram.
Area of parallelogram = Base x height = 9 x 3 =27
Answer D.

Answer is D as base is 9 and height is 3 if we plot on graph so area of quadrilateral is B*H= 9*3= 27. Oa plz
