$\:\:$

• Length of rectangular field is 48.3 m

• Breadth of the rectangular field is 29.6 m

$\:\:$

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

$\:\:$

• Cost of fencing the field at the rate of Rs 8 per m.

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

$\:\:$

To find the cost of fencing we need to calculate the length of fence required to cover the field , which can be calculated by measuring the perimeter of rectangular field

$\:\:$

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

$\:\:$

➠ 2(L + B) ⚊⚊⚊⚊ ⓵

$\:\:$

Where ,

$\:\:$

• L = Length

• B = Breadth

$\:\:$

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

$\:\:$

• L = 48.3 m

• B = 29.6 m

$\:\:$

⟮ Putting the above values in ⓵ ⟯

$\:\:$

➜ 2(L + B)

$\:\:$

➜ 2(48.3 + 29.6)

$\:\:$

➜ 2(77.9)

$\:\:$

➜ 155.8 m

$\:\:$

• Hence the length of fence required is 155.8 m

$\:\:$

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

$\:\:$

➠ Fence required × Rate of fencing

$\:\:$

• Fence required = 155.8 m.

• Rate of fencing = Rs 8 per m.

$\:\:$

So,

$\:\:$

➜ Cost of fencing = 155.8 × 8

$\:\:$

➨ Cost of fencing = Rs 1246.4
