  • A \(\sqrt{2239cm}\)
  • B \(\sqrt{2}\) x 2239cm
  • C \(\frac{\sqrt{3}}{2}\) 2239cm
  • D \(\sqrt{3}\) x 2239cm
  • E 4478cm
Correct Answer: Option D
Explanation:
x = \(\sqrt{-2239^2 + 2239^2}\)
= -\(\sqrt{10026242}\)
= 3166.42
y = -\(\sqrt{10026242 + 5013121}\)
= -\(\sqrt{15039363}\)
= 3878
= \(\sqrt{3}\) x 2239
