So it has an area of two. And then this triangle right over here is the same area as the first one. It's going to have a base of one, a height of two. So it's one times two times 1 1⁄2. Remember, the area of a triangle is 1 1⁄2 base times height, so it's one. So if you add up those areas, one plus two plus one is four. And so you might be tempted to say, oh, is this going to be equal to four?
