Solution

The correct option is B 80,000 m2
Length of diagonal = distance covered in 4 min = 6×1000×460=400m
Therefore, area of the field = 12×diagonal2=12×400×400=80,000m2
Hence, option (b) is the correct answer

विकर्ण की लंबाई = 4 मिनट में तय की गयी दूरी = 6×1000×460=400m
इसलिए, क्षेत्र का क्षेत्रफल = 12×diagonal2=12×400×400=80,000m2
