The original area :
Original length× Original Breadth
= 50×36 = 1800 m² .
Now,
New Area :
New length = 50+2 = 52 m
New Breadth = 36+2 = 38 m
New Area = 52×38 = 1976 m² .
Area of path = New Area - Original Area = 1976-1900 = 76 m
Cost of leveling 1 m² = ₹ 3.25
Cost of leveling 76 m² = ₹3.25×76 = ₹ 247
