In the two$-$dimensional body illustrated, the gradient at surface $A$ is found to be delT $/$

dely$=32\frac{K}{m}.$ What is del$\frac{T}{d}$elx at surface $B$ in $\frac{K}{m}?$ You can assume the body is at steady$-$

state with no internal heat generation. Black lines represent insulated boundaries. Heat

transfer only occurs across the orange boundaries $($A and B$).$ In your work, show

whether $T_A$ or $T_B$ is higher and explain why.
