solution please!!!
Looks fishy to me, Triangle CAB will have same area as ADB. So usually to find the area of the former we would add area of ACE and AEB would give the answer. However, in this question we have been given CDE instead of AEB. Both of which are similar (equi-angular) however not congruent. believe question does not give us enough information. Where is this question from? and do you know the answer choices? I think the naming of the quadrilateral has gone wrong, though I may be wrong here too.
Question is wrong for sure. You can find out area of CDB but not ADB.
