Question

find the perimeter. mi
4mi 2mi
9.5mi
6mi

Explanation:

Step1: Calculate the perimeter of the outer rectangle

The outer rectangle has length \(9.5\) mi and width \((4 + 2+2)\) mi. The formula for the perimeter of a rectangle is \(P = 2\times(\text{length}+\text{width})\). But we also need to account for the inner segments.
The outer - length contribution: \(2\times9.5\)
The outer - width contribution (excluding the indented part for now): \(2\times(4 + 2)\)
The inner vertical segments: \(2\times2\) (the two vertical sides of the indent)

Step2: Sum up all the segments
