---
given:
y = 2x^2 - 13x - 24
---
factoring the quadratic:
y = (2x + 3)(x - 8)
---
roots:
x = 8
x = -(3/2)
---
the negative root doesn't fit the problem, so use the positive root:
---
the x dimension of the rectangle = 8 m
---
however:
---
y = 2*8*8 - 13*8 - 24 = 0
as expected for a quadratic root
---
the problem statement appears to contain an error.
