Answer 12

The steps on finding the answer

Answer 13

Its becasue the original area number was multiplied by 2 to have the answer 160 as the new area number. Just divide the new number by 2 and you get your original area number which is 80 square feet

Answer 14

I know that 16divided by 2 is 8 so then when I got 8, I added the 0 on the end to get 80
