so I know VTN is 1.5V and its enhancement mode.

I also found Kn = 126 uA/V^2

But I got stuck.... How can I calculate W/L ?

I know the equation is Kn = Kn' (W/L)

but I dont know Kn' either.

from chegg textbook solution just says W/L = 125/100 = 1.25/1

(?????????????????????)

How ?! where did 125 and 100 come from???????

Please help.
