Hope it help you
Step-by-step explanation:
Breadth of rectangle 50m
Let length be l
The cost of of fencing 18 per metre
The total cost 4680
Perimeter of Rectangular plot = 4680/18
=260
The perimeter is given by 2(l+b)=260
=2(l+50)=260
=l+50
=130
l =80.
The length of rectangular plot is 80m
The area of plot is given by lb=(80)(50)
=4000m².
Cost of leveling for 1m² is 7.6m²
Cot of lrvrling for 4000m² =4000×7.6
=30400Rs.
The cost of leveling is 30400Rs.
