## Area of Octagon given perimeter Solution

STEP 0: Pre-Calculation Summary
Formula Used
area = 2*((Perimeter/8)^2)*(1+sqrt(2))
A = 2*((P/8)^2)*(1+sqrt(2))
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Perimeter - The perimeter of a figure is the total distance around the edge of the figure. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Perimeter: 20 Meter --> 20 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = 2*((P/8)^2)*(1+sqrt(2)) --> 2*((20/8)^2)*(1+sqrt(2))
Evaluating ... ...

## What is an octagon?

Octagon is a polygon in geometry, which has 8 sides and 8 angles. That means the number of vertices is 8 and the number of edges is 8. All the sides are joined with each other end-to-end to form a shape. These sides are in a straight line form; they are not curved or disjoint with each other. Each interior angle of a regular octagon is 135°

## How to Calculate Area of Octagon given perimeter?

Area of Octagon given perimeter calculator uses area = 2*((Perimeter/8)^2)*(1+sqrt(2)) to calculate the Area, The Area of Octagon given perimeter formula is defined as measure of the total area that the surface of the object occupies of octagon, where A=2a^2/sqrt(2)-1 where a is side and A is area of octagon. Area and is denoted by A symbol.
