A farmer wants to fence a triangular field with sides 60 m, 111 m, and 123 m. If the cost of fencing is ₹18 per meter, what will be the total expense?
Show answer & explanation
Correct answer: A
Explanation
Given:
Sides of the triangle = 60 meters, 111 meters, 123 meters
Cost of fencing = Rs. 18/meter
By the formula:
Perimeter = sum of sides
Perimeter = 60 + 111 + 123 = 294 meters
Total cost = Perimeter × cost per meter
Total cost = 294 × 18 = 5292
Total cost = Rs. 5292.
