Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a rectangle is $P = 2(l + w)$, where $l$ is length and $w$ is width. Here $l = 36$ inches and $w=22$ inches.

Step2: Substitute values

$P=2(36 + 22)$.
First, calculate inside the parentheses: $36+22 = 58$. Then, $P = 2\times58$.

Step3: Calculate result

$2\times58=116$ inches.

A. 116 inches
