Question

Find the area of a regular octagon with a side length of 15 inches. Please show work. Thank you :D

Answer 1

Answer: 1086.396 inches squared

Explanation:

Hi there,

The area formula for an octagon is:

`A=2s^(2) (1+√(2) )`

With "A" representing area and "S" representing side length.

You are given the side length, so just plug that in for "S" and input it into your calculator. It should look something like this:

`A=2(15)^(2) (1+√(2) )\\`

A= 1086.396 inches squared.

I hope this helps.

Good luck :)
