I am with C

sides will be
2S/sqrt(3) 2s 4S/sqrt(3)

as sides has to be in ratio
1 sqrt(3) 2

I dont understand, the a 30-60-90 triangle should be:

s+2s+s√3 then it should be 3s+s√3 = s(3+√3)

the answer is C.
i think as the question says the longer side and not the longest, the trick is there.
So as figured out, the sides are in ratio 1:√3:2
so C matches the perimeter.
