Question

question 20 find the perimeter of the polygon... 26 m 15 m 15 m 32 m a 88 m b 47 m c 390 m d 32 m

Explanation:

Step1: Recall perimeter formula

Perimeter of a polygon is sum of side - lengths.

Step2: Identify side - lengths

The side - lengths are 15 m, 26 m, 15 m, and 32 m.

Step3: Calculate perimeter

$P=15 + 26+15 + 32$
$P=(15 + 15)+(26 + 32)$
$P = 30+58$
$P = 88$ m

Answer:

A. 88 m
