Answer:

p=2(l+b)

Step-by-step explanation:

=2(25+15)=80.cost of fensing =80×10=800

Answer 2

Answer:

=> Rs. 800

Step-by-step explanation:

As per the data given in the question, we have to find the fencing cost.

Given that:-

For a rectangle,

Length is $25$m,

Breadth is $15$m,

We know that,

The perimeter of rectangle = 2 [ $l+b$  ]

=> $2[25+15]$

$=>2[40]$

$=> 80$m

According to the question,

The cost of $1$m is $10$ rupees,

Therefore,

The cost of $80$m:

=> $80\times 10$

=> Rs. $800$

Hence, the fencing cost is Rs. 800.
