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

18

4680

=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)

4000m

2

Cost of leveling for 1m

2

is 7.6m

2

Cot of lrvrling for 4000m
