Explanation:

Step1: Recall the perimeter formula for a rectangle

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

Step2: Identify the length and width

From the diagram, the length of the rectangle is \( 11 \) cm and the width is \( 1 \) cm.

Step3: Substitute the values into the formula

Substitute \( length = 11 \) cm and \( width = 1 \) cm into the formula: \( P = 2\times(11 + 1) \).
First, calculate the sum inside the parentheses: \( 11 + 1 = 12 \).
Then, multiply by 2: \( 2\times12 = 24 \).

Answer:

24
