Question

the area of a square field is 60025 m square A man cycles along with boundary at 18 km per hour in how much time will return to the starting point

Answer 1

60025m = 60.025km

18km - 1hr
60.025km - ?

= time = 60.025 * 1hr / 18

= 3.3hr..

Answer 2

Hey friend, Harish here.

Here is your answer:

Area of square = side²
 
          60025   = side²
 
∴ Side of the square field = √60025
                                         = 245 m.
 
So, the perimeter of square field = 245 ×4 
                                                    = 980 m
                                                    = 0.98 Km

Given that,

Speed of cyclist = 18 km/hr
 
Distance need to be covered = Perimeter of square field = 0.98 km

We know that,

$speed = \frac{distance }{time}$

Then,

[tex]time = \frac{distance}{speed} [/tex]

        $= \frac{0.98}{18}hours$

        $=0.054 hours$

   
Therefore the time taken to reach the starting point is 0.054 hours.
