Answer 1

Given: The length of rectangular field is 62m and breadth of rectangular field is 33m at 16 per metre.

⠀

Need to find: The cost of fencing a rectangular field.

⠀

⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀⠀

⠀

We know that, if we are given with the length of rectangular field and breadth of rectangular field, we have the required formula, that is,

⠀

$\sf{:\implies Perimeter_{(rectangle)} = 2(l + b)}$

⠀

⠀⠀⠀⠀ Here l is the length of rectangle & b is the breadth of rectangle, And here in this question we have l = 62m & b = 33m.

⠀

By using the required formula and substituting all the given values in the formula, we get:

⠀

$\sf{:\implies \mathcal{P}erimeter_{(rectangle)} = 2(62 + 33)} \\ \\ \\ \sf{:\implies \mathcal{P}erimeter_{(rectangle)} = 2(95)} \\ \\ \\ \sf:\implies \boxed{\purple{\frak{Perimeter_{(rectangle)} = 190}}}$

⠀

Now,

⠀

The cost of fencing a rectangular field:

⠀

$\sf{:\implies \mathcal{C}ost = 16 \times \mathcal{P}erimeter_{(rectangle)}} \\ \\ \\ \sf{:\implies \mathcal{C}ost = 16 \times190} \\ \\ \\ \sf:\implies \boxed{\pink{\frak{Cost = 3040}}}$

⠀

$\sf{\therefore \underline{The\: cost\: of\: fencing \:a\: rectangular\: field\: is\:\textsf{\textbf{Rs.3040}}}}$

Answer 2

Answer:

Given :-

• A rectangular field whose long is 62 m and wide is 33 m at Rs 16 per metre.

To Find :-

• What is the cost of fencing of a rectangular field.

Formula Used :-

$\sf\bold{\pink{Perimeter\: of\: Rectangle =\: 2(Length + Breadth)}}$

Solution :-

Given :

• Length = 62 m
• Breadth = 33 m

According to the question by using the formula we get,

↦ $\sf Perimeter\: of\: Rectangle =\: 2(62 + 33)$

↦ $\sf Perimeter\: of\: Rectangle =\: 2(95)$

↦ $\sf Perimeter\: of\: Rectangle =\: 2 \times 95$

➠ $\sf\bold{\green{Perimeter\: of\: Rectangle =\: 190\: {m}^{2}}}$

Hence, the perimeter of a rectangle is 190 m².

Now, we have to find the cost of fencing of a rectangular field :

$\dashrightarrow$ So, the cost of fencing of a rectangular field at Rs 16 m²,

$\implies$ $\sf Rs\: 16 \times 190$

$\implies$ $\sf\bold{\red{Rs\: 3040}}$

$\therefore$ The cost of fencing of a rectangular field is Rs 3040 .
