Question

Find the cost of fencing a rectangular Park of length 250m and breadth 100m at the rate of 10 per metre

Answer 1

Given :

• The cost of fencing a rectangular Park of length 250 m with 100 m.
• The rate of Rs 10 per metre.

To find :

• The cost of fencing a rectangular Park =?

Formula Used :

• Perimeter of the rectangle = 2(length +breadth)

Step-by-step explanation :

As We know that,

Perimeter of the rectangle = 2(length +breadth)

It is Given that,

The cost of fencing a rectangular Park of length 250 m with 100 m.

Substituting the values in the above formula, we get,

= 2(250 + 100)

= 2 × 350

= 700.

Therefore, Perimeter of the rectangular park = 700 m.

Now,

The cost of fencing a rectangular Park,

= 700 × 10

= 7000.

Therefore, the cost of fencing a rectangular Park = Rs. 7000.
