i made PQ, QR, and RS = x
which would mean ST = 2x
but then 5x does not go into 36 ...

Great job that you got it right, so far.
5 does not go into 36, but who said that the answer had to be a whole number?
x = 36/5 = 7.2
QS = 2x = 2*7.2 = 14.4
If this is a multiple choice problem, then you will find your answer among the choices and all worries should be gone.
If this is a grid-in, fill in 1 then 4 then a point and then another 4. The reason that a decimal point in one of the grin-in options is because not all answers will be whole numbers.

Maybe an easier approach at it would be
3x + y = 36.
3x/3 + y = 36/3
y = 12.

36 - 12 = 24.
24/3 = 8.

Therefore; PT=36, PQ/QR/RS=8 ST=12.

*Unlike the other answers, mine comes out to a whole number and it fits*

Hi,

PQ = QR = RS = x

QS = ST = 2x

PQ + QR + RS + ST =

x + x + x + 2x = 36

5x = 36

x = 7.2

QS = QR + RS = 7.2 + 7.2 = 14.4 <==ANSWER

I hope that helps!! :-)

Why do you think the answer must be an integer? Your work is correct
and x = 36/5 = 7.2. So the length of QS is 2x = 14.4.
