Question

Find the cost of fencing a square park of side \(250\) \(m\) at the rate of Rs \(20\) per metre.

Answer 1

\(\text{Side of square}\) = \(250\) \(m\) 
Perimeter \(\text{of square}\) = \(4 \times \text{side}\) 
= \(4 \times 250 \)
= \(1000\) \(m\) 
\(\text{Since, cost of fencing of per meter}\) = \(₹\) \(20\) 
\(\text{Therefore, the cost of fencing of 1000 meters}\) 
= \(20 \times 1000\) 
= \(₹\;20,000\)
