Answer:
2^n pieces
80 / (2^n) in²
Explanation:
If she cuts the paper in half 1 time, she will have 2 pieces.
If she cuts the paper in half 2 times, she will have 4 pieces.
If she cuts the paper in half 3 times, she will have 8 pieces.
So the pattern is 2^n.
The original area is 80 in². Divided by 2^n pieces means each piece has an area of 80 / (2^n) in².
