And so what is the area going to be? Well, the area is just going to be your base times your height times 1 half. So let me write that down. So the area there, the area is just going to be the base, which is square root of 2 over 2 times our hypotenuse, times the height, which is square root of 2 over 2 times our hypotenuse, times 1 half. If we didn't do that 1 half, we'd be figuring out the area of this entire square. But this is obviously, we're concerned with the triangle. So what's this going to be?
