The area \( A \) of a triangle can be calculated using the formula:

\[
A = \frac{1}{2} \times \text{base} \times \text{height}
\]

In this case, we know the area \( A = 33 \, \text{mm}^2 \) and the height \( h = 11 \, \text{mm} \). We can rearrange the formula to solve for the base \( b \):

\[
b = \frac{2A}{h}
\]

Substituting the known values into the formula:

\[
b = \frac{2 \times 33}{11}
\]

\[
b = \frac{66}{11}
\]

\[
b = 6 \, \text{mm}
\]

Thus, the length of the base of the triangle is \( \boxed{6} \) mm.
