Answer:

187.74\:\mathrm{cm}

Step-by-step explanation:

The area of a rectangle is given by l\cdot w. Therefore, we can set up the following inequality:

l\cdot 16 \leq 3,003.84.

Solving this inequality, we have:

l \leq 187.74.

Therefore, the largest length Carmen's painting can be is \fbox{$187.74\:\mathrm{cm}$}.
