Question

The cost of fencing an equilateral triangular park is Rs 24000.If each side of the park is of length 40 m, then what is the rate of fencing?

Answer 1

side=40
perimeter=40×3=120
total cost=24000
cost per m =24000÷120
=₹200 per metre

Answer 2

Rate of Fencing is Rs. 200 per meter

Step-by-step explanation:

Given.

Length of Equilateral triangular park (L) = 40 m

We know that the Perimeter of Triangular Park = Sum of all Sides

Since its an equilateral park with all sides of equal length,

Perimeter of Park = 3 x 40 m

                          P = 120 m

Total Cost of Fencing = Cost of 1 m x Length of Boundary

So, Cost of fencing = Rate of Fencing x 120

⇒ Rate of Fencing = $\frac {Cost\ of\ Fencing} {120}$

⇒ Rate of Fencing = $\frac {24000}{120}$

⇒ Rate of Fencing = 200

Hence, Rate of Fencing is Rs. 200 per meter
