I'm going to assume they want to find the area of triangle ABD? I can't quite see the end part of the question as for it is not visible.

Area of quad. ABCD = Area of triangle BDC + Area of triangle ABD

36 = (5)(8)/2 + Area of triangle ABD

36 - 20 = 16 = Area of triangle ABD.

Choose C.

Note that the Area of triangle BDC was (5)(8)/2 because 8 was the base and 5 was the height. And as every GMAT taker should know, the area of a triangle is (1/2)(base)(height).
