Question

In figure, A path 2.5m wide runs along inside the boundary of a square field whose each side is 65m. The path is to be manured. find the total expenses involved , if the cost of covering the path with red gravel is

Answer 1

path=2.5m
side=65m
area=65×65m=4225
area excludes=
area=65-2.5m=62.5m
side exclude path is 62.5
area=62.5×62.5m
3906.25
area of field exclude path is
4225-3906.25
field=318.75

Answer 2

Explanation:

Answer:

→ Area of the path = 861 m² .

Step-by-step explanation:

Given :-

→ Width of path = 3.5 m .

→ Side of square park along with path = 65 m .

To find :-

→ Area of the path .

Solution :-

∵ Side of square park without the path = 65 - ( 2 × 3.5 )  =  58 m .

Now, area of square park alnog with path

= side × side .

= ( 65 × 65 ) m² .

= 4225 m² .

And, area of square park without path

= side × side .

= ( 58 × 58 ) m² .

= 3364 m² .

Therefore, area of the path = ( 4225 - 3364 ) m² .

= 861 m² .

And, cost of measuring the rest of the field = 3364 × 25 .

= ₹86100 .

Hence, it is solved .
