Sorry about my handwriting,
hope this helps but I’m not too sure it’s correct.
also later on, i realised that you have to use 5s.f to get accurate answer
so for the area of triangle CDB, it’s 22.652
and for the area of DBA, it’s 13.555
so in the end, add both of them together and you get 22.652+13.555=36.2cm²(3s.f)

sorry for the confusion:)
ALSO sorry if it’s wrong too, I really tried my best to help
