Question

Bind the perimeter of a regular octagonal park
whose side is 42m​

Answer 1

Answer:

The perimeter of a closed, plane figure is the distance around it at its boundary. A regular octagon is a polygon, i.e., a closed, plane figure, that has 8 sides all of which are congruent, i.e., all 8 sides are equal in length; therefore, the perimeter of a regular octagon in which one of its eight congruent sides has a length of 8 meters (m) is calculated as follows:

P = 8s, where s the length of one of the 8 congruent sides of the regular octagon.

= 8(8 m)

= 64 m is the perimeter of a regular octagon whose side length is 8 m.
