Answer 1

Answer:

₹ 231000

Step-by-step explanation:

Area of road = Area of the outer circle of park - Area of the inner circle of park

Area of road = πR^2 - πr^2

Area of road = 22/7*(42+3.5)^2 - 22/7*42^2

Area of road = 22/7*45.5^2 - 22/7*42^2

Area of road = 6506.5 - 5544

Area of road = 962.5 $m^{2}$

Cost of constructing the road @ ₹240 per $m^{2}$ = ₹231000
