Question

The area of a square field is 60025 m2. A man cycles along its boundary at 18 km/h. in how much time will he return to the starting point​

Answer 1

Answer: 49 second.

Step-by-step explanation:

area of square field = 60025 m2.

length of sides of square field = under root 60025 m2.

                                                  = 245 m2.

speed of man     = 18 km/h = 18x 5/18 = 5 m/s.

time taken to complete one round = 245/5 sec.

                                                          = 49 second.
