Question

a path 2 metre wide surrounds a garden 20 by 10 metre find the area of the path​

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.

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

Answer 2

Answer:

Are of path = (20 × 2)×2 + (6×2)×2

= 40 × 2 + 12 × 2

= 80 + 24

= 104 m^2..
