Question

A rectangular park is 100m long and 120m wide.
There is a swimming pool of length 40mx30m in
this park and a circular path whose inner and outer
radius are respectively 40m and 30m. What will be
the cost of putting grass in the remaining part of
the park at Rs. 45 per m2?​

Answer 1

Answer:

483172.65

Step-by-step explanation:

Area of park= (100×120) = 12000 m2

Area of pool= (40×30) = 120 m2

Area of 40m radiused path= 251.33 m2

Area of 30m radiused path= 188.5 m2

So, area of the path= (251.33-188.5) = 62.83 m2

Remaining part= (12000-120-62.83) = 10737.17 m2

1 m2 = 45 Rs

10737.17 m2 = (10737.17×45) Rs

= 483172.65
