I would say that a is 8 since 8 plus 8 equals 16.

Do you mean a-squared or twice-a..?
----------
"twice-a":
2a=16
a=8
----------
"a-squared":
a^2=16
a=sqrt(16)
a=4
----------
hope this helps,
good luck

ignore dizzydee's solution - it is badly wrong!

answer is:
--> take square root of both sides
OR --> taking a square root ALWAYS generates 2 answers!!! So,

a=+4 or a=-4
