## Area of a Octagon Solution

STEP 0: Pre-Calculation Summary
Formula Used
area = 2*(1+sqrt(2))*(Side)^2
A = 2*(1+sqrt(2))*(s)^2
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Side - The side is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Side: 9 Meter --> 9 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = 2*(1+sqrt(2))*(s)^2 --> 2*(1+sqrt(2))*(9)^2
