Video transcript
- [Instructor] So right
over here, I have a flower and I have a ruler and what I wanna do is figure
out how wide this flower is. So you can pause the video and think about how I would do that. All right, now let's do this together. So if I wanna figure out
how wide the flower is, first I could say, all right, the left side of the
flower goes about this far. So let me draw a line here just
so we can really keep track of how far we go to the left and then the right side of the
flower goes about that far. So let's keep track of that and then we can use our
ruler to measure the distance between those two lines. We can rotate it a little bit then I'm going to move it a little bit and I want the left edge of the ruler to start at that left line. So starting right over
here and then we could see that it's one, two, three inches roughly to get us to the right side. So it looks like this
flower right over here is three inches wide.
