$\large\underline{\underline{ \sf \maltese{\:Question:-}}}$

➺If the length of a rectangle is 20m and its breadth is 15m.

➠Find the cost to fence it at rs 50 per meter

$\large\underline{\underline{ \sf \maltese{\: Answer:-}}}$

$\sf\pink{Given:}$

• length of rectangle is 20 m.

• breadth of rectangle is 15 m.

• rate of fencing is Rs 50 per m.

$\sf\pink{To\:find:}$

• cost of fencing the rectangle ?

Explanation :

Perimeter of rectangle = 2 ( l + b )

$\longrightarrow\sf{ 2\times ( 20 + 15 )}$

$\longrightarrow\sf{ 2\times 35}$

$\longrightarrow\sf{ 70}$

perimeter is 70 cm.

Cost of fencing = Perimeter × rate

$\longrightarrow\sf{ 70\times 50}$

$\longrightarrow\sf{ 3500}$

Therefore the cost is Rs 3500 .

Answer 2

Answer:

➺Perimeter = 70 m

➠ Cost of fencing=₹ 3500

Step-by-step explanation:

Solution -

➵ㅤLet's find the perimeter of the rectangle with the given dimensions.

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

$2(15 + 20) \\ \\ = 2 \times 35 \\ \\ 70 \: m$

So, the perimeter is 70m.

ㅤ

➵‎ ㅤLet's find the cost of fencing now.

$70 \times 50 \\ \\ = 3500$

So, cost of fencing is ₹3500.
