Area of square = 1600 m²

length of side, l = √1600 = 40m

so diameter of semicircles = length of side of square = 40m

radius, r = 40/2 = 20m

Area of one semicircle =

Area of all 4 semicircles = 4×628.57 = 2514.28 m²

total area = 2514.28+1600 = 4114.28

rate = Rs. 1.25 per m²

total cost = 1.25×4114.28 =**Rs. 5142.85**

length of side, l = √1600 = 40m

so diameter of semicircles = length of side of square = 40m

radius, r = 40/2 = 20m

Area of one semicircle =

Area of all 4 semicircles = 4×628.57 = 2514.28 m²

total area = 2514.28+1600 = 4114.28

rate = Rs. 1.25 per m²

total cost = 1.25×4114.28 =
