Question

Find the cost of fencing an equilateral triangle shaped park of side 50 metre at the rate of ₹ 20 per metre.

• A. ₹ 3000
• B. ₹ 1500
• C. ₹ 1000
• D. ₹ 4500

Answer 1

The correct option is A ₹ 3000

Total length of wire required to fence the field
= Perimeter of the triangular field
= 3 $\times$ Length of one side

Hence, total length of wire required to fence the field
= $3\times 50=150m$

$\therefore$ Total cost = $150\times 20=₹3000$
