Hi, I don't feel very confident about my work in this calculus problem and I would appreciate it if anyone else could note any c
orrections or ways to improve my answers. My problem is split into parts A, B, C, and D and my work is in green. Thank you!

You're pretty close. It's all in the details.
A. Correct.
B. Correct.
C. Sign error in the boxed answer. -(-0.5) = 0.5
The graph shows c ≈ 1.855. If a is more than that and decreasing, area is increasing. The sign of dA/dt will be positive. (Compare to D)
D. Units are not shown. Numerical value is correct.
