Fine the cost of fencing the square park of side length 125 m at the rate of Rs. 12 per metre​

Answer 1

$Given \: side \: of \: a \:square \:park = 125 \:m$

$Fencing \: required \: for \: park \\= Perimeter \: of \:a \:square \\= 4 \times (side) \\= 4\times 125\:m \\= 500 \:m$

$Cost \: ot\: fencing \: 1 \:m = Rs \:12$

$Now, Cost \: ot\: fencing \: 500\:m \\= 500\times Rs \:12\\= Rs \: 6000$

Therefore.,
