Question

Joey bought a triangular land for farming. The edges of the land measure $135$ m, $65$ m, and $100$ m. To protect the farm from wild animals, he decides to build a fence around the farm. If the cost of fencing is ₹200 per metre, total cost of fencing will be:

• A. $\text{₹}60,000$
• B. $\text{₹}30,000$
• C. $\text{₹}1,00,000$
• D. $\text{₹}80,000$

Answer 1

The correct option is A $\text{₹}60,000$

Perimeter of the Triangular farm

$=(135+65+100)$ m

$=300$ m

Cost of fencing = Perimeter of farm $\times$ Cost of fencing per metre

= ₹ $300\times 200=\text{₹}60,000$
