![]() Then, select one of them so it is highlighted. To start, add media assets to the timelineĭrag and drop the videos or images you'd like to crop from the media library of your video editing project onto the timeline. The same principles apply to Clipchamp for work accounts. Scale factor of the size to go from five thirds toįive, you multiply by three.Note: The screenshots in this article are from Clipchamp's personal version. So notice, when we have the area growing by a factor of nine, the And so our Rectangle N would look like this,Īnd what is its area? Well five thirds times three Five thirds is one and two thirds, so it'd go about that high, it would look something like that. So that would be three, and its height instead of being five, So a rectangle if we were to scale it up by a factor of three, we get rectangle P. That is scaled down from P by a factor of three. Now let's verify that weĪnswered their question but I just want us to feel good about it. So one way to thinkĪbout it is scale factor, scale factor squared is going to be equal to nine, or another way to think about it, our scale factor is going The idea that area will grow, the factor with which area grows is the square of the scale factor. Scale factor if our area grew by a factor of nine? Well we just talked about Notice N area is five, N's area is five square units, P's area, we just figured out is 45 square units, and so we have it growingīy a factor of nine. If we're going from anĪrea of five square units to 45 square units, you So our area, let me write this down, so N area to P area, N area to P area, we are Now, Rectangle N had anĪrea of five square units. Is, one, two, three, four, five, six, seven, eight, nine wide, and so its area is equal to 45. ![]() Two, three, four, five, it's five high, and it They gave us Rectangle P right over here, and let's think about its dimensions. What scale factor did James use to go from Rectangle N to Rectangle P? So let's think about it. James drew a scaled version of Rectangle N and labeled it Rectangle P. So Rectangle N has anĪrea of five square units. Here we're told, Rectangle N has an area of five square units. If it was scaled by a factor of two, then our area would have If it was scaled by one third, then the area would be scaled, or the area would be one ninth. To be the square of that and so one half squared is one over four. Is if you scale something, if you scale the sides ofĪ figure by one half each, then the area is going One half squared is one fourth and so the area has been changedīy a factor of one fourth or another way to answer this question, Polygon Q's area is whatįraction of Polygon P's area? Well it's going to be oneįourth of Polygon P's area. The area is going to change by the square of that. Q's area is one fourth of Polygon P's area and that makes sense because when you scale the dimensions of the Polygon by one half, To be two times four which is equal to eight. Scaled it by one half, and now what is our area going to be? Well our area, and this Polygon Q, and so our area is going In the scaled version is going to be four. Over here being eight, the corresponding side So instead of this side beingįour, it's going to be two and instead of this side Now let's create Polygon Q, and remember, Polygon Q is a scaled copy of P using a scale factor of one half. Here, it's a quadrilateral, it's in fact a rectangle and its area is just going Here is equal to eight, this is Polygon P right over Right over here is four and this side right over So let's say that this is, and I'm gonna scale it by one half so I'm gonna make its sides So Polygon P, let's just say, I'm just gonna createĪn arbitrary polygon. ![]() Since we're talking aboutĪrea, I like to deal with rectangles since it's easy to think about areas of rectangles. Practice, you might be able to do it without drawing pictures but they're saying someĪrbitrary Polygon Q and P so let's just make a simple one. Make this a little bit tangible and once we get some ![]() Polygon Q's area is whatįraction of Polygon P's area? Pause this video and see We're told that Polygon Q is a scaled copy of Polygon P using a scale factor of one half.
