What scale factor takes trapezoid D to trapezoid E?

Question

(Trapezoid D side lengths: 5 1/3, 7, 12)
(Trapezoid E side lengths: 4 1/5, 3, 1/5, 7 1/5)

Answer 1

To find the scale factor that takes trapezoid D to trapezoid E, we need to compare the corresponding side lengths of the two trapezoids.

We will compare the longest bases of each trapezoid:

12/7.2 = 1.7

Therefore, the scale factor that takes trapezoid D to trapezoid E is 1.7.
