The area of a square field is 60025 msq. A man cycles along its bounda...
Solution:
Finding the side of the square field
To find the side of the square field, we need to take the square root of its area.
√60025 = 245
Therefore, the side of the square field is 245 m.
Finding the perimeter of the square field
The perimeter of the square field is the sum of all its sides.
Perimeter = 4 × side
Perimeter = 4 × 245
Perimeter = 980 m
Converting the speed of the man
The speed of the man is given in km/h. We need to convert it to m/s to make calculations easier.
18 km/h = 5 m/s
Finding the time taken by the man
To find the time taken by the man to return to the starting point, we need to divide the perimeter of the square field by the speed of the man.
Time taken = Perimeter / Speed
Time taken = 980 / 5
Time taken = 196 seconds
Therefore, the man will take 196 seconds or 3 minutes and 16 seconds to return to the starting point.
Final Answer
The man will take 3 minutes and 16 seconds to return to the starting point.
