Question

What the perimeter for a regular pentagon with the 1/2 meters

Answer 1

$2P=2.5m$

1) Assuming the side length of that Regular Pentagon is 1/2

2) Then we can write the following formula:

$\begin{gathered} 2P=5a \\ 2P=5(\frac{1}{2}) \\ 2P=2.5m \end{gathered}$

Thus the perimeter is 2.5m
