## Area of Decagon given perimeter Solution

STEP 0: Pre-Calculation Summary
Formula Used
area = (5/2)*((Perimeter/10)^2)*(sqrt(5+2*sqrt(5)))
A = (5/2)*((P/10)^2)*(sqrt(5+2*sqrt(5)))
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 = (5/2)*((P/10)^2)*(sqrt(5+2*sqrt(5))) --> (5/2)*((20/10)^2)*(sqrt(5+2*sqrt(5)))
Evaluating ... ...

## What is a decagon

Decagon is a polygon with ten sides and ten vertices. A decagon, like any other polygon, can be either convex or concave, as illustrated in the next figure. A convex decagon has none of its interior angles greater than 180°. To the contrary, a concave decagon (or polygon) has one or more of its interior angles greater than 180°. A decagon is called regular when its sides are equal and also its interior angles are equal.
