Given that length of playground = 62 m 60 cm
= 62.6 m [Since 10 cm = 0.1 m]
Breadth of a playground = 25 m 40 cm
= 25.4 m
Area of a playground = Length x Breadth
= 62.6 m x 25.4 m
= 1590.04 m2
Given rate of turfing = Rs. 2.50/ m2
Total cost of turfing = (1590.04 x 2.50)
= Rs. 3975.10
Perimeter of a rectangular field = 2(Length + Breadth)
= 2(62.6 + 25.4) = 176 m
Distance covered by the man in 3 rounds of a field = 3 x Perimeter of a rectangular field
= 3 x 176 m = 528 m
The man walks at the rate of 2 m/sec.
Speed of man walks = 2 x 60 m/min = 120 m/min
Thus, required time to cover a distance of 528 m = 528/120
= 4.4 min
= 4 minutes 24 seconds [Since 0.1 minutes = 6 seconds]
Anyone answer for the second question.
