Question

the area of square field is 60025m^. A man cycles along its boundary at 18 know. In how much time will he return to starting point? ​

Answer 1

Area of square = a^2 = 60025 m^2
a= 245 m
so

4a= 245* 4 = 980 m
Now speed is 18km / h or 5 m/s
Time = 980/ 5 = 196sec ans

Answer 2

Step-by-step explanation:

Area of square field = 60025 m sq

side of field = √60025

= 245 m

Perimeter of field = 4 × side

= 4× 245

= 980 m

A man cycles at the speed of = 18 km/h or 5 m/sec

Time taken to return to starting point = 980/5

= 980/5

= 196 seconds
