A rectangular park is 100m by 50m. It is surrounded by semi-circular flower bed sall round. Find the cost of leveling the semi-circular flower bed sall 60paise per square meter.

Length of rectangular park = 100m


Breadth of rectangular park = 50m


Radius of flower bed along length of park =


Area of flower bed along length of park =



Radius of flower bed along width =


Area of flower bed along width =


Total area of flower beds = 7850+1962.50 = 4812.50m2


So,


Cost of leveling semicircular flower beds = 9812.50×.60 = Rs 5887.50
