1.	In a rectangular plot of land 70 m long and 40 m broad, a circular garden of radius 17.5 m is developed. Find the cost of turfing the remaining portion at the rate of Rs.28.50 per sq. metre.
Answer» Answer: Rs 52379.78 Step-by-step explanation: 1st question: AREA of the plot = 70×40 = 2800 m^2 area of circular gardan = π(17.5)^2 = 962.11 m^2 hence, the REMAINING area=2800-962.11=1837.88 m^2 so the cost of TURFING = 1837.88×28.50 =Rs 52379.78

Answer:

Rs 52379.78

Step-by-step explanation:

1st question:

AREA of the plot = 70×40 = 2800 m^2

area of circular gardan = π(17.5)^2 = 962.11 m^2

hence,

the REMAINING area=2800-962.11=1837.88 m^2

so the cost of TURFING = 1837.88×28.50

=Rs 52379.78
