And we want to know, what is the perimeter of ABCD? So let me write it down. The perimeter of rectangle ABCD is just going to be equal to the sum of the lengths of the sides.

And I'll do perimeter here on the left, and I'll do area here on the right. And you're probably pretty familiar with these concepts, but we'll revisit it just in case you are not.

This is also going to be 2w over here.

And we know that AB is equal to 7, and we know that BC is equal to 5.

Let's do a couple more of these.

28 meters.

It's designed it seems to envelope the entire human heart.

Well one way to realize it is that the pier , the perimeter's the distance all the way around the rectangle.

Perimeter

So this right here, this is just a formula for the perimeter of a rectangle.

Round them up.

We become indifferent out of self preservation, and as a numbed reaction to the complexity and chaos around us.

You are too negligent of those around you.

You'll get something like this. Eventually, as the heart gets really big, you get something like this.

Environmental viscosity

Let's say I have another circle here.

Each iceberg has its own individual personality.

What I want to do in this video is a fairly straightforward primer on perimeter and area.

Of a jet...

So all we're interested in here is comparing the temperature of the beetle against the background.

How do we inspire everyone around us?

The way to interpret this apparently simple graph is, on the vertical is an indication of how complex caregiver utterances are based on the length of utterances.

McGee, David... Perimeter.

You come with me. McGee, take the perimeter.

Be kind to those around you.

You might be wondering 'How do you get a layer that has a gap within it?' Let me try to show you what happens in a fetus.

Feel my heart.

The pond was encircled with trees.

We have to figure out its length as well. So, how do we figure that out?

So let me draw a square here. My best attempt. So this is A, B, C, D. And we're going to tell ourselves that this right here is a square.

No! Right and might are on our side.

Area and Perimeter

It means greedy.

Fringing on your territory?

Computer Aided Design, Computer Aided Manufacturing.

He might need surgery

What's the matter with him?

Now that heart.

My heart!

My heart.

The lake is ten miles about.

Remember, a seamount turns into an island when it hits the surface. And what's the context of the Phoenix Islands?

I photographed this thing last week in Dorset.

Anyway, we're done.

So it's equal to 28 centimeters square or squared centimeters.
