Question

find the perimeter.
12 ft
4 ft
p =? ft

Explanation:

Step1: Recall perimeter formula

For a rectangle, $P = 2(l + w)$ where $l$ is length and $w$ is width.

Step2: Identify length and width

Here, $l = 12$ ft and $w = 4$ ft.

Step3: Substitute values

$P=2(12 + 4)$.

Step4: Calculate inside parentheses first

$12+4 = 16$.

Step5: Multiply

$P = 2\times16=32$.

Answer:

32 ft
