Answer:
See image
Step-by-step explanation:
The new trapezoid will be smaller than the original. Each side will be 2/3 of the original. The top is length 3 originally so times that by 2/3. When you multiply a whole number times a fraction, just multiply the whole (big) number times the top number in the fraction. A fraction bar is just dividing.
If you know how to cancel, you can do that instead.
See image for calculations of new side lengths. Sorry I didn't draw the new one. It is the same shape, just smaller.
