${\large{\purple{\mathbb{ANSWER}}}}$

☆ Given:-

• Cost of leaving a square lawn = 13322.5

• Rate of leaving the lawn = 2.5/m².

☆ To find:-

• The cost of fencing at the rate of 5/m.

☆ Now,

• Let the side of Square Lawn be S.

☆ So Acc. To Que.

=》 2.5 × S × S = 13322.5

{Since area of square = Side²}

=》 S × S = 13322.5/2.5

=》 S² = 5329

=》 S² = (73)²

${\boxed{\red{=》 \:\:S \:\:=\:\: 73\:\: units.}}}$

Therefore area of the Lawn

= 4 × Side

= 4 × S

= 4 × 73

${\large{\boxed{\red{= \:\:292 \:\:meters.}}}}$

Also,

• Cost of fencing 1 meter = 5.

Therefore,

Cost of fencing 292 meters

= 5 × 292

${\boxed{\red{\large{=\:\: 1460.\:\:Rupees}}}}$

Therefore cost of Fencing Square Lawn is Rupees 1460.
