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
!

Answer:
x = -4
Step-by-step explanation:
16 = 4*4 = 4²
64 = 4 * 4* 4 = 4³

As bases are same, compare exponents
6x + 48 = -6x
Subtract 48 from both sides
6x = -6x - 48
Add '6x' to both sides
6x + 6x = -48
12x = -48
Divide both sides by 12
x = -48/12
x = -4
