Question

Regular polygons have congruent sides and congruent angles. The regular octagon has a perimeter represented by the expression shown. A regular octagon is shown. The perimeter is equal to forty-eight y minus 40. Write an expression to represent the length of one side of the octagon.

Answer 1

Answer:

a = 6y - 5

Step-by-step explanation:

The sides and the angles of a regular polygon are congruent.

The perimeter of a regular octagon is given by (48y - 40).

Let each side of the regular octagon is a, then its perimeter will be equal to 8a.

Hence, 8a = (48y - 40)

⇒ a = 6y - 5.

So, this is the expression to represent the length of one side of the octagon. (Answer)
