Question

Find the cost of fencing a rectangular park of length 175 m and breadth 125 m at the rate of Rs 12 per metre.

Answer 1

Length of rectangular park = \(175\) \(m\) 
Breadth of rectangular park = \(125\) \(m\) 
Perimeter of park = \(2 \times (length + breadth)\) 
= \(2 \times (175 + 125)\) 
= \(2 \times 300 = 600\) \(m\) 
Since, the cost of fencing park per meter = \(₹ \;12\)

Therefore, the cost of fencing park of \(600\; m = 12 \times 600\) 
= \(₹\; 7,200\)
