You need to split the shape up into separate pieces so you can find their areas easily. I have shown this and the working out in the picture.
To find the measurements of the sides of the triangles, I just did 7-6=1 and 14-8=6 to find the missing lengths. So, your answer is 90 units^2
I think it is D
Hope my answer help you?
If 75% = 108 then
100% = 81
The postulate you can use to prove that those triangles are congruent is the SSS. Since BC and AD are congruent (given), AB and DC are congruent (given), and AC and AC are congruent (i forgot which postulate it is, however, it states that the same line is congruent with itself)
hope this helps

82 is the median
