Question

in a rectangular plot of land 70m long and 40m broad. a circular garden of a radius 17.5m is developed. find the cost of turfing the remaining portion at the rate of rupees 28.50per sq. m

Answer 1

The answer of this would be 682.5

Answer 2

Area of the plot = 70×40 
                         = 2800 m²
area of circular gardan = π(17.5)^2 
                                      = 962.11 m²
so,
the remaining area=2800-962.11
                              =1837.88 m²
so the cost of turfing = 1837.88×28.50 
                                 =Rs 52379.78
