Question

If trapezoid WXYZ is dilated to form trapezoid ABCD, what is the scale factor used for the dilation.(Write the scale factor is decimal form)

Answer 1

Answer:

1.25

Explanation:

The new length of WZ is calculated as the scale factor times the length of AD, then we can calculate the scale factor as the following division:

$\text{scale factor = }\frac{WZ}{AD}$

Then, the scale factor is:

$\text{Scale Factor = }\frac{10\text{ ft}}{8\text{ ft}}=1.25$

So, the answer is 1.25
