The area of the remaining portion of the land is 92 sq.m.
and the cost of the leveling is Rs.2760000
Step-by-step explanation:
Length of land = 12 m
Breadth of land = 9 m
Area of land =12×9=108 m^2
Side of square flowerbed = 2m
Area of 1 square bed = side^2=>2^2=>4 m^2
Area of 4 square bed = 4×4=>16 m^2
Area of remaining portion = 108m^2-16m^2= 92m^2
Cost of leveling 100 sq.cm. = Rs.3
Cost of leveling 0.0001 sq.cm. =Rs.3
Cost of leveling 92 sq.m. = [tex] \frac{3}{0.0001}\times 92 [/tex] =Rs.2760000
Hence the area of the remaining portion of the land is 92 sq.m. and the cost of the leveling is Rs.2760000
