$\underline{\underline{\huge{\gray{\tt{\textbf Answer :-}}}}}$

$\:\:$

$\sf\large\bold{\orange{\underline{\blue{ Given :-}}}}$

$\:\:$

• Length of rectangular field = 24 m

• Breadth of rectangular field = 20 m

$\:\:$

$\sf\large\bold{\orange{\underline{\blue{ To \: Find :-}}}}$

$\:\:$

• Cost of ploughing the field at Rs 18 per sq.m.

$\:\:$

$\sf\large\bold{\orange{\underline{\blue{ Solution :-}}}}$

$\:\:$

To calculate the cost of ploughing the field we need to have the area in which ploughing is required which can be found by measuring the Area of rectangular field

$\:\:$

$\underline{\bold{\texttt{Area of rectangle :}}}$

$\:\:$

➠ L × B ⚊⚊⚊⚊ ⓵

$\:\:$

Where ,

$\:\:$

• L = Length

• B = Breadth

$\:\:$

$\underline{\bold{\texttt{Area of rectangular field :}}}$

$\:\:$

• L = 24 m

• B = 20 m

$\:\:$

⟮ Putting the values in ⓵ ⟯

$\:\:$

➜ L × B

$\:\:$

➜ 24 × 20

$\:\:$

➜ 480 sq. m.

$\:\:$

• Hence the area of rectangular field is 480 sq. m.

$\:\:$

$\underline{\bold{\texttt{Cost of ploughing :}}}$

$\:\:$

Rate of ploughing × Area needed to be ploughed

$\:\:$

➜ 18 × 480

$\:\:$

➨ Rs 8640

$\:\:$

• Hence the cost of ploughing is Rs 8640
