Question

a path 5 m wide runs along inside a square Park of side 100m .Find the cost of cementing the path at the rate of ₹100 per 10m square​

Answer 1

Answer:

Rupees 5000

Step-by-step explanation:

Length of path = 100m

Breadth = 5 m

Area = L × B

Area = 500m^2

cost of cementing 10m^2 = 100 Rs.

cost for 1m^2 = 100/10 × 1

cost for 500m^2 = 10 × 500

= 5000 Rs.

Answer 2

Answer:

19000rupee

Step-by-step explanation:

area of path = 100*100- 90*90

                    = 100000-8100

                    =1900

cost =100*1900/10

        = 19000rupee
