Question

Joy takes 2km to run around a square park. Find the area of the park. Also, find the cost of levelling it at Rs. 6.50 per metre square.
(With solution).

Answer 1

Joy runs 2 km around the square park,

2 km = 2 x 1000 = 2000 meters

Now 2000 m is the perimeter

And perimeter of square is 4a, where a is the side of the square

so, 4a = 2000

a = 2000/4 = 500

we get side as 500 m

Now area of square = side x side = 500 x 500 = 250000 m²

Cost of leveling = Rs. 6.5 per m²

So cost of leveling 250000 m² = 250000 x 6.5 = Rs 1625000

Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

STEP 1: Find the perimeter:

Perimeter = 2km (Given)

Perimeter = 2 x 1000 = 200 m

Perimeter = 4 x Length

2000 m = 4 x Length

Length = 2000 ÷ 4

Length = 500 m

.............................................................................................

STEP 2: Find the area:

Area = Length x Length

Area = 500 x 500

Area = 250000 m²

.............................................................................................

STEP 3: Find the cost of levelling the park:

1 m² = Rs 6.5

250000 m² = 6.5 x 250000 = Rs 1,625,000

.............................................................................................

Answer: It costs Rs 1,625,000 to level the park.
