Rectangle A’B’C’D’ is the image of rectangle ABCD after dilation. What is the scale factor of the dilation?

The scale factor of the dilation is 3

Step-by-step explanation:

we know that

A dilation is a non rigid transformation that produce similar figures

so

Rectangle ABCD and rectangle A'B'C'D' are similar

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional

Let

z ----> the scale factor

we have

----> difference of x-coordinates

 ---> difference of x-coordinates

substitute

The scale factor is greater than 1

so

The dilation is a enlargement

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
