Question

rectangular plot is 40 m long and 16 board road of uniform width of 2 metres around the plot inside it find the cost of covering the road with bricks and Rupees 15 per square metre and also find the cost of covering the remaining part of the plot with grass at rupees9per square metre​

Answer 1

Answer:

First, we find the area of the rectangular plot.

Area=l*b= 40*16 =640m^2

Then we find the area of the rectangular plot without the path of 2m. So we'll have to subtract 4 from the length and breadth(4 because the path is running on two sides of the length and breadth).

Area = (l-4) *(b-4)= (40-4)* (16-4)= 36*12= 432m^2

Therefore, area of the path= Area of the rectangular plot-area of the rectangular plot without the path= 640-432=208 m^2

Therefore, price of paving the path at Rs. 15 per metre square= 15*208= Rs. 3120

Cost of covering the remaining part with grass at Rs 9 per square metre= 432*9= Rs. 3888.
