Question

find the perimeter of the polygon. 20 m 11 m 11 m 26 m a 68 m b 37 m c 26 m d 220 m

Explanation:

Step1: Recall the formula for perimeter

Perimeter of a polygon is the sum of all its side lengths.

Step2: Add the side lengths

The trapezoid has side lengths \(11\) m, \(20\) m, \(11\) m, and \(26\) m. So, \(P = 11+20 + 11+26\).
First, \(11+20=31\), then \(31+11 = 42\), and \(42+26=68\).

Answer:

A. \(68\) m
