The image shows a trapezoid with the following side lengths:

• Top side: 13 inches
• Left side: 9 inches
• Right side: 7 inches
• Bottom side: (not explicitly given but inferred as a straight horizontal side)

To calculate the perimeter $P$ of the trapezoid, we add all the sides together:

$P = 13 \, \text{in} + 9 \, \text{in} + 7 \, \text{in} + \text{bottom side}$

However, the length of the bottom side isn't given. If we assume the bottom side is parallel and equal in length to the top side (13 inches), we can calculate:

$P = 13 \, \text{in} + 9 \, \text{in} + 7 \, \text{in} + 13 \, \text{in} = 42 \, \text{in}$

Thus, the perimeter of the trapezoid is 42 inches.
