Question

A rectangular grassy lawn measuring 40 m by 25 m is to be surrounded externally by a path

which is 2 m wide. Calculate the cost of leveling the path at the rate of Rs 8.25 per square metre.

Answer 1

Answer:

Rs 2277

Step-by-step explanation:

Find the area of the lawn :

Area = Length x Breadth

Area = 40 x 25 = 1000 m²

Find the area of the lawn and the path :

Area = Length x Breadth

Area = (40 + 2 + 2) x (25 + 2 + 2) = 1276 m²

Find the area of the path :

Area = 1276 - 1000 = 276 m²

Find the cost:

1 m² = Rs 8.25

276 m² = 8.25 x 276 = Rs 2277

Answer: Rs 2277

Answer 2

Answer:

Area of path = Area of field with path - Area of field without path

Area of field with path = (l + 2) * (b + 2)

=(40 + 2) * (25 + 2)

= 42 * 27

= 1134 m²

Area of field without path = l * b

=40 * 25

= 1000 m²

Therefore,

Area of path = 1134 - 1000

= 134 m²

Cost of leveling the path = 134 * 8.25

= ₹ 1105.5

Hope this helps.....
