Answer:
Length of the play ground.= 75m 20 cm = 75.20m
Breadth of the playground = 34 m 80 cm = 34.80m
Therefore area of the playground =(75.20×34.80)m square =2616.96m per square
Perimeter of the playground = 2 (75.20+34.80)m
2(110)m = 220m
1. Cost of levelling =rs 1.50×2616.96
=rs 3/2×2616.96
= rs(3×1308.48)
2. Distance travelled to go round the field once =220m
Therefore to go round to the field 3 times= 3× 220= 660m
(660÷1.5 secs ) (t = d/s )
=(660÷15/10) sec = 660×10/15
=440 secs = 440/60 min
= 22/ 3 minutes = 7 min 20 secs
