You have 3 different length spokes on a bike.
Front and the 2 rears.
You can Google a spoke calculator and input your SPECIFIC rim and your SPECIFIC hub etc., or you can remove a good spoke and measure it.

Some Trek wheels have the spoke lengths printed in small print on the rim labels, so you could take a look there first. Otherwise, what model year is your 7.1 FX, and which position(s) do you need spokes for (front, left rear, right rear)?

Tell me the rim label...
Tell me the hub brand and model...
And perhaps I'll be able to use this to figure it out:

It's fairly easy to measure if you have a built wheel and need to replace a spoke.
Measure along a good spoke from the outer lip of the hole in the hub out along to the spoke to the top of the rim. Then use a nail, pen or any slim stick to make a depth gauge, put it against the top of the nipple, and use your thumb nail to mark the outer edge of the rim. Measure that and subtract from the first for the spoke length to the top of the nipple.
If you have the nipple from a broken spoke, you can measure hub to inside edge of the nipple, and add the measured height of the nipple.
BTW- as someone who's built a good many wheels over the years, the best advice I can give you is to never ask or rely on anyone's advice about spoke length. Learn how to measure, and use a spoke calculator you know and trust to get reliable info every time. That's unless you actually like unlacing wheels and building them twice.
