Scale factor = 5 1 in inches = 5/1 inches, Scale length = 64 cm into inches = 24.4 inches. In the example below, the scale factor of triangle ABC to triangle DEF is 2. To get the second, smaller figure, we multiply 211721\times \frac{1}{7}2171; the figure on the right uses a scale factor of1:7,17\frac{1}{7}71, oroneseventh. Dilating triangle ABC by a scale factor of -2 results in triangle DEF with vertices D (-2, -6), E (-4, -6), and F (-4, -2). These problems involve multiplication or require you to simplify fractions. After solving this, the dimension of the new shape is = 12. A scale drawing is an accurate drawing of an object done using a scale factor to shrink the original object's dimensions. In this article about the scale factor, we explained the term scale and the scale factor with an example. if you can figure that out. You should have one figure of which the side lengths are given or measurable. Example: If the dimension of the larger shape is \(30\) and the dimension of the smaller figure is \(15\), then the scale factor will be \(3015=2\). The original shape has been reduced if the scale factor is less than the number \(1\). A negative scale factor makes the dilation rotate 180 and it creates an image on the other side of the centre of the enlargement. What would be the scale factor when real length is 20m to feet and scale length is 5 meters in feet? Scaling down means that a larger figure is reduced to a smaller one. Hence, you can see that the scale factor is smaller than the number \(1\). Therefore, the dilated triangle will be A'B'C' and the coordinate points obtained are A'(0, 4), B'(4, 2), C'(-4, -4). Keep in mind that the measurements are supposed to be centimeters. Ans: We have the length of the shape \({\rm{ = 6\,cm}}\) and the width or breadth of the shape \({\rm{ = 3\,cm}}\).Now, you have to increase the size of the given shape by the scale factor \(4\).So, you have to multiply the given dimensions by the number \(4\).Length \({\rm{ = 6 \times 4 = 24\;cm}}\)Breadth \({\rm{ = 3 \times 4 = 12\;cm}}\)Hence, the new increased dimensions of the shape are \({\rm{24\;cm}}\) and \({\rm{12\;cm}}\). See Herons theorem in action. Let's do another example. Measure the distance between this point and a point on a pre-image. Here, the scale factor can be calculated using the basic formula given in the above section. They gave us Rectangle P right over here, and let's think about its dimensions.
