Question

19. The area of a square field is 60025 m? A man cycles along its boundary at 18 km/h. In ho
much time will he return to the starting point?​

Answer 1

Given :

• → The area of a square field = 60025 m.
• → Speed of Cycle of man = 18km/s

Need To Find :

• → In how much time will he return to the starting point?

Formula Used Here :

• → Area of Square = (Side) ²
• → Time = Distance / Speed

Conversion Needed :

• → Speed of cycle = 18km/s
• → 18 × 1000 / 60 × 60
• → Speed of Cycle = 5m/s

According to Question :

• → (Side)² = 60025m²
• → Side = √60025m²
• → Side = 245m

Perimeter of Square :

• → Perimeter of Square = 4 × side
• → Perimeter of Square = 4 × 245m
• → Perimeter of Square = 980m

Calculating Time Taken :

• → Time = Distance / Speed
• → Time = 980 / 5m/s
• → Time = 196 sec

Therefore :

• → In 196 second he will return back to the starting point.

Answer 2

Given :

❇️The area of a square field = 60025 m.

❇️ Speed of Cycle of man = 18km/s

To Find :

☘In how much time will he return to the starting point?

Formula Used :

✍ Area of Square = (Side) ²

✍ Time = Distance / Speed

Conversion Needed :

→ Speed of cycle = 18km/s

→ 18 × 1000 / 60 × 60

→ Speed of Cycle = 5m/s

According to Question :

➡ (Side)² = 60025m²

➡Side = √60025m²

➡Side = 245m

Perimeter of Square :

⚽️ Perimeter of Square = 4 × side

⚽️ Perimeter of Square = 4 × 245m

⚽️ Perimeter of Square = 980m

Calculating Time Taken :

✴️ Time = Distance / Speed

✴️Time = 980 / 5m/s

✴️ Time = 196 sec

Therefore :

✔️ In 196 second he will return back to the starting point.
