Question

the length and breadth of a playground are 63.5 m and 36.5 respectively.how long will a man take to go round the playground thrice if he walks at the rate of 2 m/s? also, find the cost of turfing it at rs 4 per square metre.​

Answer 1

Step-by-step explanation:

perimeter=2(l+b)

2(36.5+63.5)=200m

speed=distance/time

time=d/s

time=200/2

time=100 sec

area=l*b

63.5*36.5

2317.5

cost=2317.5*4=9271m2

Answer 2

Answer:

9721m
