• Here we have been told to find the cost of leveling the field so First of all we need to find the area of the field and then we can multiply it by the cost of leveling per square meter .

$\maltese\LARGE\textsf{\underline{ GiVeN :-}}$

$\large\textsf{ }$

$\qquad\tt{:}\longrightarrow\large\textsf{Length of the square field = 135 m}$

$\qquad\tt{:}\longrightarrow\large\textsf{Rate of leveling the field = Rs.3 per sq. m}$

$\large\textsf{ }$

$\maltese\LARGE\textsf{\underline{ To FiNd :-}}$

$\large\textsf{ }$

$\qquad\tt{:}\longrightarrow\large\textsf{Total cost for leveling the field = ?}$

$\large\textsf{ }$

$\maltese\LARGE\textsf{\underline{ FoRmUla :-}}$

$\large\textsf{ }$

$\Longrightarrow\large\textsf{ {\large\textsf{Area}}_{\small\textsf{( \; Square \; )}} = \large\sf{Side^2} }$

$\large\textsf{ }$

$\maltese\LARGE\textsf{\underline{ SoLuTioN :-}}$

$\large\textsf{ }$

$\qquad\tt{:}\longrightarrow\large\textsf{ {\large\textsf{Area}}_{\small\textsf{( \; Field \; )}} = \large\sf{135^2} }$

$\qquad\tt{:}\longrightarrow\large\sf{= 135 \times 135}$

$\qquad\tt{:}\longrightarrow\boxed{\large\textsf{Area of the field = 18225 sq. m}}$

$\large\textsf{ }$

$\qquad\tt{:}\longrightarrow\large\sf{Cost \; of\; leveling\; = 18225 \times 3}$

$\qquad\tt{:}\longrightarrow\boxed{\therefore\large\textsf{Total cost of leveling = Rs. 54675}}$

Answer 2

Answer:

Given:-

Length of a side of a square field is 135 m. What will be the cost of leveling the field at a rate of ₹3 per square metre

To Find:-

The cost of leveling per square metre at the rate ₹3

Note:-

●》For getting the cost of leveling price in "square" per metre , we need to have the square area multiplied "×" by the rate

●》Per means division, so here ₹3 per metre square will be written as ₹3/ metre²

●》Area of square = $S ( side ) × S (side) \ \ or \ \ S² ( side² )$

Solution:-

Side of a square = 135 m

☆ According to note third point~

▪︎$Area \ \ of \ \ square = S × S$

▪︎$Area \ \ of \ \ square = 135 m × 135 m$

☆ After doing calculations~

▪︎$Area \ \ of \ \ square = 18,225 m²$

☆ So according to note first and second point~

▪︎Cost of leveling = Area of square × ₹3/m²

▪︎Cost of leveling = $18,225 m² × ₹3/m²$

☆ Here, m² and m² will be canceled and after doing calculations~

Cost of leveling = $₹54,675$

Answer:-

Cost of leveling the field at rate of ₹3 per metre square = $₹54,675$
