Question

find the perimeter of the figure below, in meters. (note: diagram is not to scale) answer

Explanation:

Step1: List all side - lengths

The side - lengths are 14.2 m, 12.7 m, 12.7 m, 26.9 m, 22.9 m, 14.2 m, 12.7 m, 39.6 m, 10.2 m, 12.7 m.

Step2: Sum up all side - lengths

$P=14.2 + 12.7+12.7 + 26.9+22.9+14.2+12.7+39.6+10.2+12.7$
$P=(14.2\times2)+(12.7\times4)+26.9 + 22.9+39.6+10.2$
$P = 28.4+50.8+26.9+22.9+39.6+10.2$
$P=(28.4 + 50.8)+(26.9+22.9)+(39.6+10.2)$
$P = 79.2+49.8+49.8$
$P=178.8$

Answer:

$178.8$
