Question

A path 5 m wide runs along inside a square park of side
100 m. Find the area of the path. Also find the cost of
cementing it at the rate of Rs 250 per 10 m².​

Answer 1

Answer:

Area = 1900 m²

Cost = Rs 47500

Step-by-step explanation:

Find the area of the park and path:

Area = Length x Breadth

Area = 100 x 100

Area = 10000 m²

Find the length and breadth of the park:

Length = 100 - 5 - 5 = 90 m

Breadth = 100 - 5 - 5 = 90 m

Find the area of the park:

Area = Length x Breadth

Area = 90 x 90

Area = 8100 m²

Find the area of the path:

Area = 10000 - 8100

Area = 1900 m²

Find the cost:

10 m² = Rs 250

1900 m² = Rs 250 x 190

1900 m² = Rs 47500

Answer: Rs 47500
