find the perimeter of a regular octagon with sides of 5.5cm.
To find the perimeter of a regular octagon, you need to know the length of each side. In this case, it is given that the sides of the octagon are 5.5 cm long.
The formula to calculate the perimeter of a regular polygon, such as an octagon, is:
Perimeter = Number of Sides × Length of Each Side
Since an octagon has 8 sides, and each side is 5.5 cm, you can calculate the perimeter as follows:
Perimeter = 8 × 5.5 cm = 44 cm
Therefore, the perimeter of the regular octagon with sides of 5.5 cm is 44 cm.
