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 $600\; m = 12 \times 600$
= $₹\; 7,200$
