Dimensions of playground = 80 m and 35 m respectively
(I) area = Length *breadth
area = 80*35
area = 2800m square
Cost of leveling = 4.50 rupees pe m square
therefore total cost = 2800 * 4.50
Total cost = 12600 rupees
(II) Circumference = 2( l +b)
circumference = 2(80+35)
circumference = 2*115
circumference = 230 m
Rounds taken = 3
thus total distance = 230*3 = 690 m
speed = 1.5 m per second
Time = distance / speed
Time = 690/1.5
time = 460 second
Hope you find it helpful!!
