a = asin(1/6) b = 2a b = 2asin(1/6) Where b is angle BAC cos(2asin(1/6)) = c/6 c = ⅓(17) units. Where c is AD. d = 6-c d = 6-⅓(17) d = ⅓ units Where d is CD. sin(2asin(1/6)) = e/6 e = 1.97202659437 units. Where e is BD. f = asin((1/3)/2) f = 9.59406822686° Where f is angle EBC = angle CAE. tan(9.59406822686) = g/(17/3) g = 0.95784148869 units. Or  g = 17√(35)/105 units. Where g is DE.

Notice; Since angle BDC equals angle BAC which are the opposite inscribed angles of quadrilateral ABCD. And; CD+BD = 40 units. It implies; CD+BD = AC+AB It also implies that; Area Triangle BDC = Area Triangle BAC Therefore; AC+AB = 40 units. AC = AB = ½(40) AC = AB = 20 units. Area quadrilateral ABCD is; 2(½*20*20) = 400 square units.
