Question

Find the cost of levelling a garden with sides 500m and 250m at the rate of ₹8 per m2

Answer 1

Answer:

We will be using the formula for the perimeter of a square which is 4 times its side.

Side of the square park = 250 m

The perimeter of the park = 4 × side

⇒ 4 × 250 = 1000 m

1000 m is the perimeter of the square park.

Now, the cost of 1 m fencing is ₹ 20

Hence, the cost of 1000 m fencing = ₹ 20 × 1000 = ₹ 20,000

Therefore, ₹ 20,000 is the cost of fencing a square park of side 250 m at the rate of ₹ 20 per metre.
