I'm still trying to figure it out,

but I know answer #1 isn't correct.

ACE is part of ACB.

Area of ACB is 24.

How can a part be more than the whole?

For triangle CEA, let height from CA to E be h1

For triangle DEB, let height from DB to E be h2

h1 + h2 = 6, ratio of CA/DB = 8/6 = 4/3 ie h1 = 4/3(h2)

h1 + h2 = 6 => 4/3(h2) + h2 = 7/3h2 = 6 => h2 = 18/7, h1 = 24/7

Area of ACE = (1/2)(8(24/7) = 48/7 sq units
