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 $w = 13$ cm.

Step3: Substitute values into formula

$P=2(19 + 13)$.
First, calculate the sum inside the parentheses: $19+13 = 32$ cm.
Then, multiply by 2: $P = 2\times32=64$ cm.

Answer:
