## Area of Dodecagon given diagonal across three sides Solution

STEP 0: Pre-Calculation Summary
Formula Used
area = (3*(2+sqrt(3)))*((Diagonal across three sides/(1+sqrt(3)))^2)
A = (3*(2+sqrt(3)))*((d3/(1+sqrt(3)))^2)
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Diagonal across three sides - Diagonal across three sides is a straight line joining two opposite sides which is across three sides of the given polygon. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Diagonal across three sides: 7 Meter --> 7 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = (3*(2+sqrt(3)))*((d3/(1+sqrt(3)))^2) --> (3*(2+sqrt(3)))*((7/(1+sqrt(3)))^2)
Evaluating ... ...
A = 73.5
STEP 3: Convert Result to Output's Unit
73.5 Square Meter --> No Conversion Required
73.5 Square Meter <-- Area
