The main idea is using the Pythagorean formula to find the length of line segment
.
Alr so you use the formula 
is already given and is 
and
is 
So using algebraic rules you'll get
as:

Now using the formula:
, you can find the area of tri ABD and CBD which would be
and
so add them up and you get
!
