So we're gonna get something that is less than 16 for that side and the rest of it will all be scaled by the same factor. Now with that in mind, let's do another example.
So pause the video and which of these would match if we're scaling by a factor of less than one? The scale factor for the area will be 7 2. Set up a ratio.
Method 4. Calculating with a scale 2.
These are often smaller depictions of reality. Write the answer.
Creating scale drawings. Now you might be saying okay that was pretty straightforward because we had a very clear, you could just see the distance between A and B.
So we are told that triangle A'B'C', which they depicted right over here, is the image of triangle ABC, which they did not depict, under a dilation with a scale factor of two. Not Helpful 3 Helpful 20. So that's a good starting point.
Math Basic geometry Transformations, congruence, and similarity Dilations. What was the scale factor? So the area of the actual dining room is 1,600 times larger, and so if the drawing had an area of 1, then the area of the actual dining room would be 1,600 So what would I have to multiply each of the dimensions by to get an area factor of 1,600?
