A rectangular plot is 45 M long and 18 with a white a path of uniform width of 2.5 M surrounds the plot inside it find the cost of paving the road with bricks at rupees 15 per square metre and also the cost of covering the remaining part of the plot with grass at rupees 9 per square metre
Answers
Answer:
Total cost to pave road will be Rs 2456.25
Total coast for covering the plot with grass is Rs 7290
Step-by-step explanation:
The given data :-
Length of rectangular plot = 45 meter.
Width of rectangular plot = 18 meter.
Width of road which surrounds plot = 2.5 meter.
Length of whole plot including road = length of rectangular plot + width of road = 45 + 2.5 = 47.5 m.
Width of whole plot including road = width of rectangular plot + width of road = 18 + 2.5 = 20.5 m
We have to calculate the area of rectangular plot and road.
Area of rectangular plot = length * breadth = 45 * 18 = 810 m².
Area of whole plot including road = 47.5 * 20.5 = 973.75 m².
∴ The area of road = ( Area of whole plot including road - Area of rectangular plot) = 973.75 - 810 = 163.75 m².
i) Now we have to calculate the cost of paving road with bricks.
The rate of paving road per square meter = Rs 15.
∴ The total coast to pave road = 15 * 163.75 = Rs 2456.25.
ii) We have to find cost of covering remaining part with grass.
The rate of covering the plot with grass per square meter = Rs 9.
∴ Total coast to remaining part with grass = 9 *810 = Rs 7290
Answer:
rupees 4350 rupees 4680
