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.
