Question

A regular octagon has side length 10.9 in. The perimeter of the octagon is 87.2 in and the area is 392.4 in2. A second octagon has side lengths equal to 16.35 in. Find the area of the second octagon.

Answer 1

Formula for a octagon:

`2(1+ √(2) ) a^(2)`
a = 16.35

`2(1+ √(2) ) 16.35^(2) =1290.75`
Area = 1290.75
