getcalc.com's Octagon calculator is an online basic geometry tool to find the area, perimeter and side of a Octagonal shaped polygon, in both US customary and metric (SI) units.
Steps to Find Area of a Octagon
The step by step workout for how to find what is the area of a octagon. Students may use this octagon calculator to generate work with steps for any other similar input values.Workout :
step1 Address the formula, input parameters and values
side = 10 in
step 2 Find Area of Octagon using side value
Area A = 2 (1 + √2 ) s²
= 2 x (1 + √2 ) x (10)² in²
= 2 x (1 + 1.4142 ) x 100 in²
= 2 x 2.4142 x 100 in²
Area A = 482.8427 in²
