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

Problems on Finding the Area & Perimeter of Polygon
Interior Angles of Polygon Calculator is a free online tool that displays interior angles of a polygon when the number of sides is given. BYJU’S online interior angles of the polygon calculator tool make the calculation faster, and it displays the angle measures in a fraction of seconds.
How to Use the Interior Angles of Polygon Calculator?
The procedure to use the interior angles of the polygon calculator is as follows:
Step 1:
Enter the number of sides in the input field
Step 2: Now click the button “Submit” to get the angle
Step 3: Finally, the interior angle of a polygon will be displayed in the output field
What is Meant by Interior Angles of Polygon?
When each pair of adjacent sides joined together, the angles inside the polygon are formed. It is known as interior angles of a polygon. To find the interior angles of a polygon, follow the below procedure.
- Note down the number of sides “n.”
- To find the interior angles of a polygon, use the formula,
Sum of interior angles = (n-2)×180° - To find each interior angle of a polygon, then use the general formula,
Each angle of regular polygon = [(n-2)×180° ] / n - Substitute the given side value in the formula to get the solution.
