Question

A path 2m wide surrounds a garden 20m by 10m find (1) the area of the path and(2) the cost of paving the path at rs.10 per m2

Answer 1

Answer: (1) The area of the path would be 64m^2.

(2) The cost of paving the path at rs. 10 per m^2 would be rs.640.

Step-by-step explanation:

The length of the garden= 20m

The width of the garden= 10m

The width of the path= 2m

So, the outer length of the path would become equal to 22m (20+2).

Similarly, the outer width of the path would become equal to 12m (10+2).

So,

The area of the path= area of outer rectangle-area of garden

The area of the path= 22x12-20x10

=> 264-200= 64m^2

The cost of paving the path of 1m^2= rs.10

So,

The cost of paving the path of 64m^2= 10x64= 640
