Explanation:

Step1: Identify perimeter concept

Perimeter is sum of all side - lengths.

Step2: Add all side - lengths

$8.7+12.8 + 12.8+21.5+27.4+12.8+8.7+34.3+14.6+12.8$
$=(8.7 + 8.7)+(12.8\times4)+21.5+27.4+34.3+14.6$
$=17.4+51.2+21.5+27.4+34.3+14.6$
$=(17.4+51.2)+(21.5+27.4)+(34.3+14.6)$
$=68.6+48.9+48.9$
$=68.6+(48.9\times2)$
$=68.6 + 97.8$
$=166.4$

Answer:

$166.4$
