@ElectricPavlov Thank you for working out this question!
10 is the answer.

The answer is 463 feet.
11 is the answer.
n = 20
(a).\(\sqrt{3} \over 4\)
(b).\(1 \over 2\)
(c).\(\sqrt{3} \over 4\)
\(ab + c = bc + a\\ ab - bc = a-c \\ b(a-c) = a-c \\ b(a-c) - (a-c) = 0\\ (a-c)(b-1)=0\\ a=c\\ b=1 \)
Therefore, a and c must equal to 6.5, though the question states that all of these numbers are integers.
\(6p^6 \times q^4 + 15p^4 \times q^2 + 3p^4 \times q^3 + 9p^5 \times q^2\)
\(j = {\pm \sqrt {32} - 3}\)
