Find the cost of planting grass at the rate of ₹ 15 per m^2 in an equilateral triangular park whose length of boundary is 360 m (Use √3 = 1.732)

Answer»

Answer:

Step-by-step explanation:

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 =  

⇒ Rate of Fencing =  

⇒ Rate of Fencing = 200

Hence, Rate of Fencing is Rs. 200 per meter
