The following polygon is a regular pentagon. The length of one side of the pentagon is 1,6 mm
.


Determine the perimeter of the pentagon.

To find the perimeter of a regular pentagon, we use the formula:

\[
\text{Perimeter} = \text{Number of sides} \times \text{Length of one side}
\]

For a pentagon, the number of sides is 5, and the length of one side is given as 1.6 mm. Therefore:

\[
\text{Perimeter} = 5 \times 1.6 = 8 \, \text{mm}
\]

Thus, the perimeter of the pentagon is **8 mm**.
