Q. The cost of levelling a square lawn at 15per square metre is 19935. Find the cost of fencing the lawn at 22 per metre.

$\huge{\underline{\tt{\green{ Solution-}}}}$

Area of the lawn = $\longrightarrow \tt \frac{Total\:cost}{Cost}$

$\longrightarrow \tt \frac{19935}{15}$

$\longrightarrow \tt {1329 {m}{2}}$

 

➟ Area of the square = Side × Side

➟ So, each side of the square = $\sqrt{1329}$

• Each side of the square lawn = 36.45 m

➟ Now, Perimeter of the square lawn = 4 × Side

$\longrightarrow\:4 ×36.45$

$\longrightarrow\:145.8 m$

➟ Cost of fencing the square lawn = Rs. 22 per meter

➟ Total cost of fencing the square lawn = Rs.(145.8 × 22) = Rs. 3207.6

• So, total cost of fencing the square lawn is Rs. 3207.6
