Answer 2

Answer:

Step-by-step explanation:

Given :-

Distance traveled by Pravin = 2 km

Cost of leveling at per m²  = Rs 7

To Find :-

Cost of leveling

Formula to be used :-

Perimeter = 4 × Length

Area = Length × Length

Solution :-

⇒ Distance = 2 × 1000

⇒ Distance = 2000 m

⇒ Perimeter = 4 × Length

⇒ 2000 m = 4 × Length

⇒ Length = 2000/4

⇒ Length = 500 m

Now, Area of Park

⇒ Area of Park = Length × Length

⇒  Area of Park = 500 × 500

⇒ Area of Park = 250000 m²

Then, Cost of leveling at per m² = Rs 7

⇒ Cost of leveling at per m² = 7 × 250000

⇒ Cost of leveling at per m² = Rs. 1750000

Hence, The cost of leveling the park at 7 per m² is Rs. 1750000.
