14. A rectangular park is 104 m long and 56 m wide. Anjali walks around it at the rate
of 4 km/h. What time will she take in making 5 rounds of the park?​

Answer 1

Answer:

perimeter of rectangle=2(l+b)

2(104+56)m

2(160)m

320m

then distance of rounds=320m

time=distance/speed

time=320/4

time=90min
