• Welcome to math with Mr. J In this video, I'm going to cover how to find the perimeter of a composite figure. And remember, perimeter is the distance around a two-dimensional figure. And two-dimensional means flat. So, we have two examples that we're going to go through together in order to get this down. • Example 1 So, let's jump into number one here, where we have a figure with a bunch of different sides there. When it comes to composite figures, it's a little more complex than just finding the perimeter of a simpler figure like a rectangle or triangle, where we just have four or three sides. Here, we need to be very organized and keep track of the sides that we're adding up in order to calculate perimeter. And remember, in order to calculate perimeter, we add up all the sides. I have a hint up top: these are the most common mistakes when it comes to these types of problems. Don't forget any of the sides and don't count anything twice. I'll show you a couple of strategies in order to avoid those mistakes. Let's start with the eight feet up top. I'll come down here and write: eight plus. Now, in order to make sure I don't forget anything or count anything twice, I can circ...
