Gɪᴠᴇɴ:-Tᴏ Fɪɴᴅ:-Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ:-Sᴏʟᴜᴛɪᴏɴ:-→→ Total cost = Rs.13322.5

→ Area of Square = (Total Cost) / (Rate) = (13322.5)/2.5 =

5329m².So,→73m.## _________________

Now,→→ Perimeter of Square = 73 * 4 =

292m.Therefore,→Rate of fencing = Rs.5/m.→ Total cost of fencing = 5*292 =

Rs.1460(Ans.)Hence,TotalcostofFencingisRs.1460.➠ Rate of levelling = ₹2.5/m

➠Total cost = ₹13322.5

➠ Area of square = (Total cost/Rate)

➠Area of square = 13322.5/2.5

➠Area of square =

5329m²Then,

➠Each side of square = √5329

➠ Each side of square =

73 mNow,

➠Perimeter of the square = 73 × 4

➠Perimeter of the square =

292mSo,

➠Rate of Fencing = ₹ 5/m

➠Total cost of Fencing = 5 × 292 m

## ➠Total cost of Fencing =

₹1460
