Answer
$\mathrm{C} < \mathrm{B}=\mathrm{E} < \mathrm{A} < \mathrm{D}$
Work Step by Step
Observe 16-4, $\Delta L=\alpha L_{0}\Delta T$.
All plates have the same $\alpha$ and $\Delta T$, so $\Delta L$ is proportional to $L_{0}$, in either direction.
The increase of the area of a plate is proportional to the initial area.
The ranking is the same as the ranking of initial areas.
plate A: $\quad 3\mathrm{L}^{2}$
plate B: $\quad 2\mathrm{L}^{2}$
plate C: $\quad \mathrm{L}^{2}$
plate D: $\quad 6\mathrm{L}^{2}$
plate E: $\quad 2\mathrm{L}^{2}$
