    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
