Question

what is the perimeter of the rectangle? 19 cm 17 cm a 36 cm b 72 cm c 62 cm d 323 cm

Explanation:

Step1: Recall perimeter formula

The perimeter formula of a rectangle is $P = 2(l + w)$, where $l$ is the length and $w$ is the width. Here $l = 19$ cm and $w=17$ cm.

Step2: Substitute values

$P=2(19 + 17)$.
First, calculate the sum inside the parentheses: $19+17 = 36$ cm.
Then, multiply by 2: $P = 2\times36=72$ cm.

Answer:

B. 72 cm
