help me pls whit this

Answer:
The Perimeter??? its 51.39 I think.
Step-by-step explanation:
So... Perimeter for a circle is pi(3.14) times the diameter so 9x3.14 is 28.26 then u divide by 2 (because its half a circle) then u get 14.13 then times 3 (because there is three half circles) which is now 42.39 then u add 9 (from that square and only 9 because its asking for perimeter) which the result is 51.39
