To find the perimeter of the given figure, we need to add up the lengths of all the outer sides.

Let's break it down based on the measurements provided:

1. Starting from the bottom left and moving clockwise:

   • Bottom: $1 \text{ cm} + 3 \text{ cm} + 8 \text{ cm} = 12 \text{ cm}$

2. Right side:

   • Bottom part: $3 \text{ cm}$
   • Top part: $5 \text{ cm}$
   • Total right side: $3 \text{ cm} + 5 \text{ cm} = 8 \text{ cm}$

3. Top side:

   • $6 \text{ cm}$

4. Left side:

   • Bottom part: $4 \text{ cm}$
   • Middle part: $2 \text{ cm}$
   • Top part: $3 \text{ cm}$
   • Total left side: $4 \text{ cm} + 2 \text{ cm} + 3 \text{ cm} = 9 \text{ cm}$

Now, sum all these lengths:

$12 \text{ cm} + 8 \text{ cm} + 6 \text{ cm} + 9 \text{ cm} = 35 \text{ cm}$

So, the perimeter of the figure is 35 cm.
