Speed = 4km/h
time = 3 minute = 3/60 h
distance covered = speed × time = 4 × 3/60 = 1/5 km = 1000m/5 = 200m
So the diagonal (विकर्ण) = 200m
side = diagonal/√2 = 200/√2 = 100√2 m
Area(क्षयत्रफल) = side^2 = (100√2)^2 = 20000 m^2
time = 3 minute = 3/60 h
distance covered = speed × time = 4 × 3/60 = 1/5 km = 1000m/5 = 200m
So the diagonal (विकर्ण) = 200m
side = diagonal/√2 = 200/√2 = 100√2 m
Area(क्षयत्रफल) = side^2 = (100√2)^2 = 20000 m^2
