a = 12.43

Step-by-step explanation:

Given

A = 15 --- the Apothem

n =8 ---- number of sides

Required

The length of each side (a)

The relationship between A and a is:

$a = A * 2\tan(\frac{180}{n})$

This gives:

$a = 15 * 2\tan(\frac{180}{8})$

$a = 15 * 2\tan(22.5)$

a = 15 * 2 * 0.4142

a = 12.426

a = 12.43 --- approximated
