Length of the pond through the path = (50+10) = 60 meter
Breath of the pond through the path = (38+10) = 48 meter
Area of the pond through the path
= (l*b)
=(60*48)m^2
=2880 m^2
Area of the pond
=(l*b)
=(50*38)m^2
=1900 m^2
Hence, area of the path
=(2880-1900)m^2
=980 m^2
Cost for leveling the path
=(980*45)rupees
=43,200 rupees
