Answer :

28 sq. units

Let A = (-4, -2), B = (-3, -5), C = (3, -2) and D = (2, 3)


We draw Line BD and divide the quadrilateral into 2 triangles


ΔABD and ΔBDC


Area of both triangles


Area ΔBDC =


=


=


=


=


=


= 16.5 units


A = (-4, -2), B = (-3, -5), D = (2, 3)


Area ΔABD =


=


=


=


=


= 11.5 units


Total area of quadrilateral = Sum of Area of triangles


= ΔBCD + ΔABD


= 16.5 + 11.5 units


= 28 sq units.
