1. ## Gɪᴠᴇɴ :-

• Cost of leveling and turning a square lawn @ of Rs. 2.50m’ is Rs. 13322.50..

## Tᴏ Fɪɴᴅ :-

• The cost of fencing it @ Rs. 5 per meter. ?

## Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ :-

• Leveling = Area of square = side * side
• Fencing = Perimeter of Square = 4 * side .

## Sᴏʟᴜᴛɪᴏɴ :-

Rate of Leveling = Rs.2.5 / m

→ Total cost = Rs.13322.5

→ Area of Square = (Total Cost) / (Rate) = (13322.5)/2.5 = 5329m².

So,

Side of Square = √(Area) = √(5329) = 73m.

## _________________

Now,

Side of Square = 73m.

→ Perimeter of Square = 73 * 4 = 292m.

Therefore,

Rate of fencing = Rs.5/m.

→ Total cost of fencing = 5*292 = Rs.1460 (Ans.)

### Hence, Total cost of Fencing is Rs.1460.

• Cost of leveling and turning a square lawn @ of Rs. 2.50m’ is Rs. 13322.50.
• Find the cost of fencing it @ Rs. 5 per meter

➠ 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 = 5329m²

Then,

➠Each side of square = √5329

➠ Each side of square = 73 m

Now,

➠Perimeter of the square = 73 × 4

➠Perimeter of the square = 292m

So,

➠Rate of Fencing = ₹ 5/m

➠Total cost of Fencing = 5 × 292 m
