Explanation:

Step1: Recall perimeter formula for rectangle

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

Step2: Identify length and width values

Here, $l = 31.74$ feet and $w=14.85$ feet.

Step3: Substitute values into formula

$P=2(31.74 + 14.85)$.
First, calculate the sum inside the parentheses: $31.74+14.85 = 46.59$.
Then, multiply by 2: $P = 2\times46.59=93.18$ feet.

Answer:

93.18 feet
