➺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:

➺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.

➵‎ ㅤLet's find the cost of fencing now.

70 \times 50 \\  \\  = 3500

So, cost of fencing is 3500.
