PLEASE HELP ME!! I NEED TO GET THIS DONE

Step-by-step explanation:

A)

Dilation. Since it's only the size of the figure that's changing

B)

Height of the smaller one: 4

Width of the smaller one: 6

Height of the bigger one: 6

Width of the bigger one: 9

6/4 = 1.5

9/6 = 1.5

Since both 6/4 and 9/6 was 1.5, that means that the Width and Height was proportional and that the two trapezoids is at a ratio o:

1 : 1.5

One unit of the smaller one is 1.5 units on the bigger one.

step-by-step explanation:

mean or average is 40.6
