Explain Scale Factor with an example.Ans: The scale factor is defined as the ratio between the dimensions of the new figure and the actual figure of a similar type.The figures size can be enlarged or reduced than the original shape using the scale factor. The scale factor of 2 represents that you will get a new shape that will be twice the size of the actual figure. Scale length = 230mm to inches = 9.05 inches, Real length = 4mm to inches = 0.157 inches, Scale factor of length = 9.05 inches/0.157 inches. If you're scaling down from a larger figure to a smaller one, use the equation scale factor = smaller length over larger length. Q.4. Thus, you can calculate a scale factor using any dimension you are given. 3x4 = 12 units squared. Example: You have a shape of a square that has \(16\) units side, and you want to reduce the size by \(25\% \) or, say, one-quarter \(\frac{1}{4}\).Here, the scale factor that is to be used is \(\frac{1}{4}\).So, the new side of the square will be \(= 16 \times \frac{1}{4} = 4\) units. It is commonly used in maps to represent the actual figures in smaller units. answered their question but I just want us to feel good about it. Scale factor is a number that is used to draw the enlarged or reduced shape of any given figure. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known. What is a scale factor of \(2\)?Ans: The scale factor \(2\) means the new shape obtained after scaling up the original figure by \(2\) or making the dimensions of the original figures shape double.Below is an example for a better understanding of the scale factor of \(2\). The scale factor is a ratio of the corresponding sides of similar shapes. Let's look at one more example and scale both up and down. Aratiomeasures the relationship between two things.
