Question

A person walks at the rate of 4 km/hr. How long will he take to go round a square park 5 times, whose
area is 2500 m?​

Answer 1

Answer:

15 mins Needed :)

Step-by-step explanation:

Area of Square Park = 2500 sq m.

Side of the park = sq rt of 2500 = 50 m.

Perimeter of the square = 4*50 = 200 m.

In round he has to travel 200 m.

So, in 5 round, he needs 5 * 200 = 1000 m to travel.

He needs 15 minutes to go 5 round of the park.  

Hope it Helps!
