miles
submit

Explanation:

Step1: Recall the perimeter formula for a rectangle

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

Step2: Identify the length and width

Here, the length \( l = 12 \) miles and the width \( w = 5 \) miles.

Step3: Substitute the values into the formula

Substitute \( l = 12 \) and \( w = 5 \) into the formula: \( P = 2\times(12 + 5) \).
First, calculate the sum inside the parentheses: \( 12 + 5 = 17 \).
Then, multiply by 2: \( 2\times17 = 34 \).

Answer:

34
