Remmber pemdas or gemdas or bodmas or whatever
exponential laws
(x^m)^n=x^(mn)
ok so
(3^2)(2a)^(3/2))^2=
(3^2)(2a)^((3/2)*2)=
(3^2)(2a))^(6/2)=
(3^2)(2a)^3=
(3^2)(8a^3)^3=
(9)(8a^3)=
72a^3

Answer:
This polygon is comprised of 30 congruent triangles, each with a central angle of 12°
And using trig, each has an area of......
(1/2)(20)^2 sin(12°) = 41.5823381636 sq ft
So, 30 times this = 1247.470144908 sq ft = 1247.5 sq ft (rounded to the nearest tenth)
