Sure! You can use a method to find the perimeter of tricky shapes! Here’s how to do it step by step:

1. Look at the Shape: First, take a close look. Is it a strange polygon? If yes, it might not have a simple formula like squares or circles.

2. Find the Sides: Measure or figure out how long each side is. For odd shapes, each side can be different lengths. Sometimes, you’ll need a ruler, especially for drawings or things in real life.

3. Add Them Together: After you know the lengths of all the sides, just add them up! The way to find the perimeter (we call it $P$) of an odd polygon is:

   $P = a_1 + a_2 + a_3 + ... + a_n$

   Here, $a_1, a_2, a_3, ..., a_n$ are the lengths of the sides.

4. Practice with Examples: One of the best ways to get better is by practicing. Try figuring out the perimeter of different shapes you see, like garden beds, playgrounds, or even room layouts in magazines.

5. Draw a Picture: Making a drawing can help you see the shape clearly and remember the lengths you find.

So, even though tricky shapes don’t have one formula like simpler shapes, you can still find their perimeter! Just remember to measure carefully and note all the sides. With some practice, you might find it fun and easy!
