Question

A Rectangular park is 40m long and 20m broad.find the cost of levelling the park at Rs.2.50 per metre ​

Answer 1

Answer:

Means he have find the perimeter of a rectangle

perimeter = 2(length+breadth)

length = 40m

breadth = 20m

perimeter = 40×2+20×2

= 80+40

= 120 ÷ 2.50

= ₹48

so the cost of levelling the park is ₹48

Answer 2

Correct Question

• A Rectangular park is 40m long and 20m broad.find the cost of levelling the park at Rs.2.50 per square metre.

⠀

Given

• Length of the rectangular park = 40m
• Breadth of the rectangular park = 20m

⠀

Solution

• For finding the levelling area of the park, we need to find the area of the park.

⠀

We know that

⠀

☆ Area = Length × Breadth

⠀

→ Area = 40 × 20

→ Area = 800m²

⠀

• Now, it is given in the question that cost of levelling the park is Rs.2.50 per square meter.

⠀

Therefore,

→ Cost = Rs.(800 × 2.50)

→ Cost = Rs.2,000

⠀

Hence,

• The total cost of levelling the park is Rs,2,000.
