Calculate the perimeter of this shape

its a compound shape (the perimeter are 12cm and 18) i need pls

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

step-by-step explanation:

no.
