Given that

➪ Area of a square field = 164025 m²

Now , Applying formula for Area of Square to calculate the measure of either side .

$\sf \:Area \: of \: a \: square field = 164025 m² \\ \sf \:Area \: of \: a \:square field \: = side \times side \\ 164025 = \sf( { side)}^{2} \\ \longrightarrow\sf \: side = \sqrt{164025} \\ \sf \:side \: = 405m$

Now , Applying the formula for the Perimeter of the square Field = 4 × side

$\sf \:Perimeter \: of \: the \: square \: Field = 4 × side \\ \sf \:Perimeter \: of \: the \: square \: Field = 4 \times 405 \\ = \sf \:1620 \: m$

Now , Cost of fencing

$\longrightarrow1 m = ₹ 15$

1620 m = ₹ (15 × 1620)

= ₹ 24300
