Question

a rectangle plot of land has dimension as 40m x 30m. there are five square flower beds each of side 2.5m. find the area of remaining plot . also find the cost of ploughing five flowers beds at the rate of Rs 25 per m2

Answer 1

The area of remaining plot and the cost of ploughing five flowers beds are 1168.75 sq.m. and Rs.781.25 respectively.

Step-by-step explanation:

Length of plot = 40 m

Breadth of plot = 30 m

Area of plot $= Length \times Breadth = 40 \times 30 = 1200 m^2$

Side of square bed = 2.5 m

Area of 1 square bed =$Side ^2 = 2.5^2 = 6.25m^2$

Area of 5 square bed = $6.25 \times 5 = 31.25 m^2$

Area of remaining plot = Area of plot - Area of 5 beds

Area of remaining plot = 1200 - 31.25 = 1168.75 sq. m.

Cost of ploughing square bed 1 sq.m. = Rs.25

Cost of ploughing square bed 31.25 sq.m. =$Rs.25 \times 31.25=Rs.781.25$

Hence the area of remaining plot and the cost of ploughing five flowers beds are 1168.75 sq.m. and Rs.781.25 respectively.
