Question

a polygon has sides of length 24 feet, 22 feet, 21 feet, 26 feet, and 23 feet. find its perimeter. perimeter = □

Explanation:

Step1: Recall perimeter formula

The perimeter of a polygon is the sum of the lengths of all its sides. So we need to add the lengths \(24\), \(22\), \(21\), \(26\), and \(23\).

Step2: Add the lengths

\[

$$\begin{align*} 24 + 22+21 + 26+23&=(24 + 22)+(21 + 26)+23\\ &= 46+47 + 23\\ &=46+(47 + 23)\\ &=46 + 70\\ &= 116 \end{align*}$$

\]

Answer:

116 feet
