Answer:
Rs 6517.14 176 sec to walk twice
Step-by-step explanation:
Length = 52 m 60 cm = 52.60 m
breadth = 35 m 40 cm = 35.40m
Area = 5260/100 × 3540/100 = 526/10 × 354/10
= 1862.04m
Perimeter = 2(52.60 + 35.40) = 176m
Aman takes 1 sec to travel 2m
2m in 1 sec
1m.in 1/2
352m in = 1/2 × 352 = 176 sec
Cost of turfing 1 sq m = 3.50
Cost of turfing 1862.04 sq m = 1862.04 × 3.50 = Rs 6517.14
