Explanation:

Step1: Calculate the perimeter

The perimeter of a shape is the sum of all its side lengths.
The side lengths of the given shape are \(1\) in, \(7\) in, \(5\) in, \(1\) in, \(5\) in, \(1\) in.

$$1 + 7+5 + 1+5 + 1$$

$$=(1 + 7)+(5 + 1)+(5 + 1)$$

$$=8+6 + 6$$

$$=20+1$$

$$=21$$

Answer:

C. 21 in.
