1. The problem statement, all variables and given/known data
The problem is given.

2. Relevant equations

3. The attempt at a solution
I tried to solve the question as if there is a nanowire between two reservoirs and got an answer. But I don't know what should I do to measure thermal conductivity in a thin film.

My formula for k in a nanowire was independent from geometry and material, just dependent to temperature. So if I say, the thin film and nanowire conductivities are the same, would this reasoning be valid?
