Question

what is the perimeter of the rectangle? 16 cm 12 cm a 66 cm b 56 cm c 192 cm d 28 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 $l = 16$ cm and $w=12$ cm.

Step2: Substitute values

$P=2(16 + 12)$.
First, calculate the sum inside the parentheses: $16+12 = 28$ cm.
Then, multiply by 2: $P = 2\times28=56$ cm.

Answer:

B. 56 cm
