An equilateral triangular plot of land has a side length of 75 meters. A landowner wants to put a rope around the entire plot. If the rope costs ₹15 per meter, what is the total expense?
Show answer & explanation
Correct answer: C
Explanation
Given:
Each side of the equilateral triangle = 75 meters
Cost of rope = ₹15 per meter
Formula:
Perimeter = 3 × side
Total cost = Perimeter × price per meter
Perimeter = 3 × 75 = 225 meters
Total cost = 225 × 15 = ₹3375
