0:00 Of this figure.
00:01 I'm assuming because you didn't give directions.
00:05 All it was was the picture of the shape.
00:07 So next time you submit a question, just make sure that you put the question that you want or next time you submit a photo, make sure you submit what you want help with.
00:18 So i'm going to find the area of this shape.
00:24 And this shape is one, two, three, four, five, six, seven, eight.
00:30 It's an octagon.
00:34 Okay.
00:35 And so an octagon is eight sides.
00:39 And you can kind of think of it as eight triangles...
