Okay, this rhombus -looking thing kind of, a diamond, i need to find the area of.
00:08
So i'm going to cut it in this way, making the two triangles in which i can find their area.
00:21
So i'm going to find the area of this upper triangle first.
00:26
Okay, its base goes from negative 3 to positive 3.
00:30
So if you think about it, it's six spaces.
00:35
Then the height of this triangle going straight up, well, goes from zero to five.
00:42
So it is five.
00:44
All right.
00:45
So base times height divided by two because we have a triangle is 15.
00:58
Okay, now i'm going to find the area of the lower triangle...
