3/4z = 2/3a
z + a = 510...z = 510 - a

3/4(510 - a) = 2/3a
382.50 - 3/4a = 2/3a
382.50 = 2/3a + 3/4a
382.50 = 8/12a + 9/12a
382.50 = 17/12a
382.50 * 12/17 = a
270 = a

z + a = 510
z + 270 = 510
z = 510 - 270
z = 240

check..
3/4z = 2/3a
3/4(240) = 2/3(270)
180 = 180 (correct)

Using the apothem, a, and the perimeter, p, the area, A, of a regular polygon is

$A = \dfrac{pa}{2}$

You need to calculate the area of the octagon and subtract the area of the square.
The perimeter is 8 times the side.

$A = \dfrac{pa}{2} - s^2$

$A = \dfrac{8 \times 13 \times 15.69}{2} - 13^2$

$A = 815.88 - 169$

$A = 646.88$
