Solution

Steps: 2 Marks
Formula: 1 Mark
Answer: 1 Mark

(i) Let $l$ be the length of the square
$\Rightarrow$ Area of square = $l^{2}$
$\Rightarrow l^{2} = 576$
$\Rightarrow l = 24 m$

(ii) Perimeter of square = 4l

$\Rightarrow 4 \times (24) = 96 m$

(iii) Cost of fixing a fence
$= ₹ (96 \times 3.20) = ₹ 307.20$
