Answers
Step-by-step explanation:
The cost of paving the path with bricks at 25 rs per square metre =2550\ rs=2550 rs
The cost of covering the remaining part of the plot with grass at 19 rs per square metre=11362\ rs=11362 rs
Step-by-step explanation:
Given: The dimension of a rectangular plot are 35 m by 20 m.
Area of the whole plot=34\times20=700\ m^234×20=700 m
2
A path of uniform width 2m is built along the border and inside it.
Area of the path= 35\times2+(20-4)\times2=70+32=102\ m^235×2+(20−4)×2=70+32=102 m
2
The cost of paving the path with bricks at 25 rs per square metre =25\times102=2550\ rs25×102=2550 rs
Area of the remaining part=700-102=598\ m^2700−102=598 m
2
The cost of covering the remaining part of the plot with grass at 19 rs per square metre=19\times598=11362\ rs19×598=11362
