Question

Four square flowerbeds each of side 2m are dug on a piece of a land 12m long and 9 m wide . find the area of the remaining portion of the land . find the cost of the levelling this land at the rate of rupees of 3 per 100cm square

Answer 1

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 =$12 \times 9 = 108 m^2$

Side of square flowerbed = 2m

Area of 1 square bed = $Side^2 = 2^2 = 4 m^2$

Area of 4 square bed = $4 \times 4 = 16 m^2$

Area of remaining portion = $108 m^2 - 16 m ^2=92 m^2$

Cost of leveling 100 sq.cm. = Rs.3

Cost of leveling 0.0001 sq.cm. =Rs.3

Cost of leveling 92 sq.m. = \frac{3}{0.0001} \times 92=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
