Question

Find the cost of fencing a square park of side 250 m at the rate of Rs 20 per metre.

Answer 1

$\textsf{Side of square = 250 m}$



$\textsf{Perimeter of square = 4 x side}$
$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \textsf{= 4 x 250}$
$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \textsf{= 1000 m}$



$\textsf{Since, cost of fencing of per meter = }$ ₹ $20$



$<b>$
Therefore, the cost o fencing of 100 metres = 20 x 1000 = ₹ 20, 000.

Answer 2

Answer:

20000 Rs.

Step-by-step explanation:

Fencing is done along the perimeter of a plot, so, we have to find the perimeter first.

It is given that a square park has a side length of 250 m.

Hence, the perimeter of the park is (4× 250) =1000 m {Since the square park has four equal sides}

Now, the rate of the cost of fencing is given to be 20 Rs. per meter.

Therefore, the total cost of the fencing is (1000×20) =20000 Rs. (Answer)
