Explanation:

Step1: Recall perimeter formula

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

Step2: Identify length and width

Here, $l = 16$ inches and $w = 14$ inches.

Step3: Substitute values into formula

$P=2(16 + 14)$
First, calculate the sum inside the parentheses: $16+14 = 30$. Then, multiply by 2: $2\times30=60$ inches.

Answer:

D. 60 inches
