Hey Mate!!

1 hectare = 10000 m^2

=> 9 ha = 90000 m^2

Area of square = side^2

=> 90000 = s^2

=> s = √90000

=> s = 300 m

Perimeter of square = 4 × side

=> 4 ×300 = 1200 m

Thus, cost of fencing at ₹4.50/m,

=> 1200 × 4.50

=> ₹5400

Hope it helps...✌✌

$\huge\boxed{\fcolorbox{fuchsia}{grey}{Solution}}$

Given,

1 Hectare = 10000m^2

=>9 ha=90000m^2

Area of square = side^2

=>90000=s^2

=>s=√90000

=>s=300m

Area of Perimeter=4×side

=>4×300

=>1200m

The cost of fencing the square field at Rs.4.50

=>1200m×4.50

=>Rs.5,400
