WebThe dimensions of our scale drawing are 6 by 8 which gives us an area of 48 square units. Notice when we found the new dimensions we multiplied the 3 and 4 EACH by the scale factor. So the new area could be found 3 x 4 x scale factor x scale factor. 48/12 = 4 which is the scale factor times the scale factor with a scale factor of 3 WebEnlargement and scale factors – nrich mapping document Enlargement resources Pdf documents Enlargements and Making Letters Power point documents Enlargement and Making Letters and Scale Factor Video about scale factors and enlargement http://www.bbc.co.uk/programmes/p02mqvq3 and teachers tv Video

WebSince the drawing is scaled down, then the scale factor should be reduced to a fraction with a numerator of 1. Multiply both the numerator and denominator by 2 to simplify. scale factor = ½” × 2 12″ × 2 = 1 24. And finally, rewrite the fraction as a ratio. scale factor = 1 24 = 1:24. Thus the scale factor for this drawing is 1:24 . WebA scale factor can be used to enlarge or reduce a shape.
