    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.

    \huge\tt{QUESTION:}

    • 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

    \rule{200}3

    \huge\tt{SOLUTION:}

    ➠ 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

    ➠Total cost of Fencing = ₹1460

    \rule{200}3
