Explanation:

Step1: Recall perimeter formula

The formula for the perimeter $P$ of a rectangle is $P = 2(l + w)$, where $l$ is the length and $w$ is the width.

Step2: Identify length and width

Here, $l = 19$ cm and $w = 17$ cm.

Step3: Substitute values into formula

$P=2(19 + 17)=2\times36 = 72$ cm.

Answer:

B. 72 cm
