But we want to know the area of the triangle.

So, do we need this?

The next thing is What about the footprint? Stewart mentioned the footprint.

So what I would do I would figure out the area of this bathroom floor, and then divide by the area of the tiles.

Surface

Area

And that's the answer.

Sector Surface

So what is our area squared going to be?

The area of Canada is greater than that of the United States.

So if we just multiply this out, let me write it here.

let's do, surface

So you recognize that wind and solar are environmentally invasive forms of energy generation?

Problem 38.

The area in central Japan.

We already know the perimeter for this purple or mauve rectangle, but we need to figure out its area.

Let me write it this way

And they tell us that the area is 168.

Requirements

Area and Perimeter

No, we used that.

So that's going to be 14 centimeters just like that.

Now this transformation has doubled the area of the original figure, and therefore we have just learned that the area of the triangle equals the area of this rectangle divided by two.

So for example, if we were going back to this rectangle right here, and I wanted to find out the area of this rectangle and the notation we can use for area is put something in brackets.

Let me write this down.

let's say, x is equal to a and x is equal to b.

Skysurfing is skydiving with a board on the feet.

Area squared is equal to ad minus bc squared.

The determinant of this is ad minus bc, by definition.

Believe it or not, he wants me off this case even more than you do.

I'm going to show you about leverage.

So we already know the area for this one, but we, we don't know its perimeter, so how do we figure that out? Well, to figure out perimeter we would need to know the lengths of all the sides.

The height squared is the height squared right there.

Now it looks like some things will simplify nicely.

So then if you try to ask questions

The height is the value of the function, which is x y squared.

Length is 1.

Because this is longer.

Fair enough.

Well, pressure is force divided by area.

Three square furgles . So it's the same exact area. Three square furgles is equal to twelve square feet.

We have the area of ABCD is going to be equal to 2 times the area of ABC, this thing right over here

Additional requirements

That makes sense because surface area is a 2 dimensional measurement. We think about how many sq cm can we fit on the surface of the cylinder.

And I'll plot it there and it'll be a point on the surface.
