Step-by-step 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 .
