Question 17 • MASTER COURSE Geometry
Divide a larger dimension by its corresponding smaller dimension to find the scale factor. For the lengths, 14.7 ÷ 4.2 = 3.5; the widths and heights give the same ratio: 20.3 ÷ 5.8 = 3.5 and 33.6 ÷ 9.6 = 3.5. The dimensions are multiplied by 3.5, or 3 and 1 half, which is choice D.
