5 ft
blank feet
submit

Explanation:

Step1: Recall perimeter formula for rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times (length + width) \). Here, the length is \( 18 \) ft and the width is \( 5 \) ft.

Step2: Substitute values into formula

Substitute \( length = 18 \) and \( width = 5 \) into the formula: \( P = 2\times(18 + 5) \).

Step3: Simplify the expression

First, calculate the sum inside the parentheses: \( 18 + 5 = 23 \). Then multiply by 2: \( 2\times23 = 46 \).

Answer:

46
