Area of road = π(R²-r²)
=(22/7)(40²-37²)
=(22/7)(1600-1369)
=(22/7)(231)
=(22)(33)
=726 m²
=(22/7)(40²-37²)
=(22/7)(1600-1369)

______________________________________________________________
Areaof the road = Ar. of the road + ar park - at of park
Ar. = 3.14 x 40x 40 - x 3.14 x 37 x37
Ar = 5024 - 4298.66
Ar = 725.34 m²
