See image below :    (check my numbers+)


The diagonal forms a 36 . 0273 angle      folding it over produces a further reduction of 36.0273  of the 90 degree angle in the corner

   resulting in an angle of the single paper of   17.9453 degrees


you have ONE side of the triangle already  :  8      

     now you can use the tan funtion to find x        then the are of the single thickness (one of them) is 1/2  8  * x
