Answer:
Step-by-step explanation:
So perimeter is all the sides added together and 9+9+12+12 is 42. So the first box is 42.
Area is the length times width. 9x12 is 108 so the second box is 108.
Dilating by a scale factor means that you multiply each side by the scale factor. So in this question 9x2 is 18 and 12x2 is 24. 18+18+24+24 is 84 which means the 3rd box (perimeter of dilated rectangle) would be 84.
Area would be 18x24 which is 432.
