    Polygon Area & Perimeter Calculator

    getcalc.com's Polygon Formulas & 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.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
