I am really curious about ways to tackle this since it is such an open ended problem.

I thought about it purely visually and after an embarrassingly long time figured out the answer to be

\begin{align*} 44 \end{align*}

I would love to hear how others think about it! I have also found a neat "rigorized" solution I would be happy to share.
