The area of a square field is 60025 m2. A man cycles along its bound

1.	The area of a square field is 60025 m2. A man cycles along its boundary at 18 Km/hr. In how much time will he return at the starting point?
Answer» The area of square field = 60025 m² Speed of cyclist = 18 km/h = 18 × (1000/60×60) = 5 m/s² Area = 60025 m² Side² = 60025 Side = √60025 = 245 Total length of boundary = 4 × Side = 4 × 245 = 980 m Now ,Time taken to return to the starting point = 980/5 = 196 seconds = 3 minutes 16 seconds

The area of a square field is 60025 m2. A man cycles along its boundary at 18 Km/hr. In how much time will he return at the starting point?

Answer»

The area of square field = 60025 m²

Speed of cyclist = 18 km/h

= 18 × (1000/60×60)

= 5 m/s²

Area = 60025 m²

Side² = 60025

Side = √60025

= 245

Total length of boundary = 4 × Side

= 4 × 245

= 980 m

Now ,Time taken to return to the starting point

= 980/5

= 196 seconds

= 3 minutes 16 seconds
