Answer 2

Given :

• A rectangular field of length 320 m and breadth 280 m metre.
• Cost of fencing at the rate of R.S 32.50 per meter .

To find :

• Find the cost of fencing a rectangular field.

Solution :

Let's find out the perimeter first.

As we know the field is in rectangular shape.

Perimeter of rectangle = 2(l + b)

Substituting the values in it, we get

$\implies$Perimeter of rectangle = 2( l + b)

$\implies$2(320 + 280) m

$\implies$2(600)m

$\implies$ 1200 m

The perimeter of field → 1200 m

So, for finding the total cost.

Simply multiply the per metre cost by perimeter.

$\implies$Perimeter → 1200 m

$\implies$1 metre cost of fencing field → Rs. 32.50

Total Cost of fencing = Perimeter × Rs. 32.50

$\implies$ 1200 × Rs. 32.50

$\implies$Rs 39,000

Therefore,

• The total cost of fencing a rectangular field is Rs. 39,000.
