Question

the area of a square piece of land is 6400 sq m.let's find cost of fencing all around the land at Rs 3.50 per meter.​

Answer 1

Answer:

₹1120

Step-by-step explanation:

Area=6400 m^2

Therefore, side^2=6400

                  side=sqrt(6400)

                  side=80m

Perimeter of land=4*side=4*80=320m

Cost of fencing= ₹3.50 per metre

So, cost of fencing land=₹3.50*Perimeter of land

                                       =₹3.50*320

                                       =₹1120
