Answer 1

Question :

The breadth of a playground is 70 m and its length is 110 m. What is the length of the fencing to enclose the playground? Find the cost of fencing at the rate 5 per meter.

Answer :

$\sf\pink{Given:}$

• Breadth of the playground is 70 m.

• Length of the playground is 110 m.

• rate of fencing is Rs 5 per m.

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

• Length of the fencing ?

• Cost of fencing it ?

Explanation :

Length of the fencing is equal to the perimeter of the playground .

Perimeter of the playground = 2( l + b )

$\longrightarrow\sf{ 2\times ( 70 + 110 )}$

$\longrightarrow\sf{ 2\times 180}$

$\longrightarrow\sf{ 360}$

• Perimeter of the rectangular playground is 360 m .

• Therefore the length of the fencing is 360 m .

Cost of fencing = Perimeter × Rate

$\longrightarrow\sf{ 360\times 5}$

$\longrightarrow\sf{ 1800}$

• Therefore the cost of fencing is Rs 1800 .

Answer 2

Step-by-step explanation:

Length of fencing = Perimeter

L= 110m and B = 70m

2*(l+b) = 2*(110+70) =2*180= 360m

• • So,length of fencing = 360m

•

Cost of fencing 1m = rs.5

Cost of fencing of 360m= 360*5 = 1800rs.

So,the cost of fencing is 1800rs.
