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
