Question

the area of a square field is 60025msq a man cycles along its boundaries at speed of 18 km/ h.in how much time will he return to the starting point​

Answer 1

Step-by-step explanation:

area of square field = 60025

one side of square field = √60025 = 245 metre.

perimeter of field = 4 * 245 = 980 metre

speed = 18 km/h = 18 * 5/ 18 =

5 metre / second

time taken to return to the starting point =

980 / 5 second .

196 second

= 3 mins + 16 second
