Answer 2

Answer:

The total cost of fencing the land is 420000 Rupees.

Step-by-step explanation:

Given,

A rectangular piece of land with dimensions length(l)=.8km

             and breadth= .6km

To find: the cost of fencing the land

we know that,

     Perimeter of the land= 2(l+ b)

Perimeter of the land=

                                     $2(0.8+0.6)\\ \\ =2(800+600)\\ \\ =2(1400m)\\ \\ =2800 m$

Wire needed to fence three rows=3×2800= 8400m

The cost of fencing is ₹50 per metre.

Therefore cost for fencing 8400m=$8400\cdot 50=420000$
