# Polygon (Area & Perimeter) Calculator

getcalc.com's polygon calculator is an online basic geometry tool to calculate area & perimeter of any polygon shape having n number of sides, in both US customary & metric (SI) units.

## Steps to Find Area & Perimeter of a Polygon

The step by step workout for how to find what is the area and perimeter of a polygon. Students may use this polygon calculator to generate work with steps for any other similar input values.Workout
step 1 Address the formula input parameter and values
Number of side n = 5
Side Length S = 10 in

step 2 Find the perimeter of the polygon
Perimeter P = S x n
= 10 x 5 in
Perimeter P = 50 in

step 3 Apply the values in below formula
Area A = S x (Perimeter/2)2 tan (180/n)

= 10 x (50/2)2 tan (180/5)in²

= 10 x 252 tan (36)in²

= 2502 x 0.7265in²

= 2501.4531in²

Area A = 172.0477 in²
