Question

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

Answer 1

Answer: 196 seconds

Step-by-step explanation:

area of the square field=60025 metre square

the area of square=(side*side)

so,one side is the square root of 60025 and it's square root is 245

so one side = 245

perimetre is 4*245=980

speed 18 km/h=5m/s

time = distance/speed

time=980/5=196

thus, answer is 196 seconds
