How can we find perimeter of a pentagon?

To do: Find perimeter of a pentagon.

Solution:

If we have a regular pentagon let say the sides of it are 4 cm each .

If we know one side of a regular pentagon, then we know the length of each side because a regular pentagon has equal sides. We can simply plug our known side into our formula:

$P=5\times s$

$P=5\times 4$

$P=20$ 

Therefore the perimeter of the pentagon is 20cm
