Answer:

Step-by-step explanation:

Given :-

Let the sides of the triangular field be a, b and c

Sides of the triangular field :-

a = 90m

b = 80m

c = 170m

Here, we've to find the length of barbed wire to fence the triangular field thrice.

So first of all, we needa find it's perimeter.

We know that,

Perimeter of a triangle = sum of all three sides

» Perimeter of triangular field = 90 + 80 + 170

= 340m

» Total length of barbed wire required to fence Hariprasad's triangular field thrice = 340 × 3

= 1020m

He needs 1020m to fence all the sides three times.

Now total cost of fencing @ rupees 50 per meter = 1020 × 50

= Rupees51000

Hence, Hariprasad has to pay Rs  51000
