    Here your solution

    Let the length be xm

    Width=50m

    Cost of fencing=4680

    Rate=18

    Perimeter=

    18

    4680

    =260

    Perimeter=2(x+50)=260

    x+50=130

    ⇒x=80m

    ∴ Length=80m

    Area=length×width=80×50

    Area=4000m

    2

    Rate of levelling=Rs.7.6/m

    Total cost=Rs.(4000×7.6)=Rs.30400
