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

1.25

Step-by-step 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 = }(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
