A rectangular plot of land is 50. the cost of fencing the plot at the rate of rupees per metre is 4680 rupees find the cost of levelling the plot at the rate of 7.6 rupees per metre square

Answer 1

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
