Question

The cost Of putting grass in a square lawn is Rs 3888 at Rs 12 per square meter. Find the length of the side of the lawn. ​

Answer 1

Answer:

$\red{\textbf{Answer :- 18m}}$

Step-by-step explanation:

$\red{\textbf{Given :-}}$

$\textsf{total cost = Rs. 3888}$

$\textsf{cost per sqm = 12}$

$\red{\textbf{To find :-}}$

$\textsf{length of the side of the lawn.}$

$total \: area \: = \LARGE \frac{3888}{12}$

$= 324$

$area \: \: of \: square \: = 324 {m}^{2}$

${s}^{2} = 324$

$s = \sqrt{324}$

$s = 18$

$\textsf{therefore,}$

$\textsf{the length of side of lawn is 18m}$

$\red{\textbf{More information :-}}$

$area \: of \: square = {a}^{2}$

$perimeter \: of \: square \: = 4a$

$diagonal \: of \: square \: = a \sqrt{2}$

Where ‘a’ is the length of a side of the square.
