can we prove the formula to find the area of an octagon

if answer is yes, then how can we prove the formula.

of course the answer is yes, assuming the formula is correct.
Now the question is, what is the formula? 
1/2((x/sinT)squared)*sinL*N
T is 360 divided by n
L is (180T) over 2
N is no of sides
Just came up with this , still only checking it though
