length of rectangular plot = 45m
breadth of rectangular plot = 18m
area of rectangular plot = 45m×18m
= 810m2
length of inside portion
of the rectangular plot. =(45 - 2 - 2)
= 41m
breadth of inside portion
of the rectangular plot. =( 18-2-2).
=14m
area of inside portion
of the rectangular plot. = 41m×14m
= 576m2
area of road = (810-576)m2. = 234m2
the cost of paving the road with bricks at Rs. 15 per square meter= Rs( 234×15)= Rs 3510
cost of covering the remaining part of the plot with grass at Rs. 9 per square. m.=Rs( 576×9)
= Rs 5184
Answer:
Area of path is 786m²
Step-by-step explanation:
Length of field=40m
Breadth " "=25m
Area=length×breadth
Area=40m×25m
=1000m²
Length of inside field(not path's) =40m-1.5m-1.5m=37m
Breadth=25m-1.5m-1.5m=22m
Area of inside field=l×b
=37m×22m
=814m²
Area of path=Area of outside field-Area of inside field
=1000m²-814m²
=786m²
Hope it helps.
