Show answer & explanation
Correct answer: D. 2916 sq. m2916 वर्ग मीटर
Explanation
Around a closed square, 36 poles make 36 gaps of 6 m, so the perimeter = 36 × 6 = 216 m. Side = 216/4 = 54 m, and area = 54² = 2916 sq. m.बंद वर्ग के चारों ओर 36 खम्भों से 6 मी के 36 अंतराल बनते हैं, अतः परिमाप = 36 × 6 = 216 मी। भुजा = 216/4 = 54 मी और क्षेत्रफल = 54² = 2916 वर्ग मीटर।More Mathematics & Numerical Ability questions
