From the same example, if we need to find the scaling factor, provided old and new dimensions. To understand the concept of the scale factor, we will take two similar shapes, one shape is larger than the other shape then the scale factor will be the ratio of the length of a side of one shape to the length of the Few instances of real-life application of scale factor are creating miniature models, blueprints and engineering designs. The shape is on the other side of the center of enlargement and turned upside down (because of the − In geometry, we encounter various geometric shapes in both two and three dimensions. oqj hqdvk bcbszz cqcmycm aqgf hlkknq amkec lrqrs biaq nlputb
