Let me keep that there.

So the area for a triangle is equal to the base times the height now this so far, base times height is the area of a rectangle.

And then this is the height, this is the height, right over here.

It's the base times the height times 1 2.

Surface

Area

The area of the triangle is 30 in 2. Find the height and base.

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

The height of a triangle is 4 inches less than the length of the base.

To the bottom of a muddy riverbed

Sector Surface

So what is our area squared going to be?

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

But then if it was transparent, we see that there are actually six sides of a cube.

What it is now is mud, and the area of the ocean floor that has been transformed from forest to level mud, to parking lot, is equivalent to the entire area of all the forests that have ever been cut down on all of the earth in the history of humanity.

Area and Perimeter

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

let's do, surface

So the height is equal to the base minus 4. That's what the first sentence tells us.

Area squared is equal to ad minus bc squared.

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

Problem 38.

The area in central Japan.

Let me write it this way

I'll end up with saying one thing.

Because this is longer.

Fair enough.

And they tell us that the area is 168.

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.

Well they told us that the height is four more than twice the base, so we can just substitute that in.

The only possible base is 10. They say find the height and the base. So the base is 10 and the height is 4 inches less, so the height is 6.

Applause

So it's equal to base I'll write capital B since we have a lowercase b there base times height.

No, we used that.

Let me write this down.

And 55 is a lot. On a per area basis,

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

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

The width is 4y, and the height here is 2y.

Skysurfing is skydiving with a board on the feet.

That they are Piles of stars stripped away by tidal interactions of galaxies in the cluster.

Algae thrived in the extreme heat, poisoning the water.

In general, if I have just any parallelogram this is kind of a tilted one, but if I just have any parallelogram, let me just draw any parallelogram right there the area is just equal to the base so that could be the base times the height.

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.
