Answer:
p = 371.13
Step-by-step explanation:
To find the perimeter of the octagon you use the following formula:
[tex]A=\frac{(p)(a)}{2}[/tex]
A: area
p: perimeter
a: apothem
By replacing the values of the parameters A and a you calculate the values of the perimeter:
[tex]p=\frac{2A}{a}=\frac{2(10391.9)}{56}=371.13[/tex]
the perimeter is 371.13
