## Work with steps to find Sides of Octagon for given Area 72

__Question:__

What is the side length of octagon, if the area is 72 square inches?

__workout :__

step1 Address the formula, input parameters and values

area = 72 in²

step 2 Find side of octagon using area value

Side S = √

√2A/2-A/2

= √

√272/2-72/2

in= √

1.4142 x 72/2-72/2

in= √

101.8224/2-72/2

in= √101.8224 - 72/2in

= √29.8224/2in

= √14.9117 in

Side s = 3.8616 in
