Answer:
80 :)
Step-by-step explanation:

Let us take the width of the paper as base, the cut she made be hypotenuse and the paper's length be perpendicular.
Here,
Hypotenuse (H) = 87 inch
Base (B) = 60 inch
Perpendicular (P) = [To be calculated]
As, we can use Pythagoras theorem to find. So by using Pythagoras theorem :
H² = P² + B²

The length of the paper is 63 inches.

Answer:
Bro it is too hard to find . Hope you understand me
The answer to your question would be 60 percent all you do is divide that and move the decimal 2 places to the left.
