<h2>
The required "option A) 
" is correct.</h2>
Step-by-step explanation:
We have,
..... (1)
To find, 
= ?
Differentiating equation (1) w.r.t. 'x', we get
![\dfrac{dy}{dx}= \dfrac{d[(3x + x^2)^5]}{dx}](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdx%7D%3D%20%5Cdfrac%7Bd%5B%283x%20%2B%20x%5E2%29%5E5%5D%7D%7Bdx%7D)
⇒ 
[ ∵

Thus, the required "option A) " is correct.
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.
