Question

the area of a square field is 60025m2. A men cycles along its boundary at 18kmph.In how much time will he return to the starting point.

Answer 1

The area if Square field is 60025 m²

So formula for side of square when area is given is →

✓area

So , Side = ✓60025
= 245 m

So, Perimeter of Square = side × 4 = 245×4 = 980m

The speed of cyclists = 18km/h = 18×5/18m/s = 5m/s

So , The Time taken by cyclists to return to the starting point will be given by →

Distance (perimeter of square in this case)/speed

= 980/5
= 196 seconds.

Answer → The cyclists will return to starting point after 196 seconds
