12. In the adjoinin
72 729 m2. A path of uniform width runs all around it. If the area
of the path is 295 m², find
(i) the length of the boundary of the square field enclosing
the lawn and the path.

Answers
Solution :-
Area of the square lawn = 729 sq m
Area of the square = Side*Side
⇒ 729 = (Side)²
⇒ Side = √729
⇒ Side = 27 m
So, the length of each side of the square lawn is 27 m
Now,
Area of the path that runs all around the square lawn = 295 sq m (Given)
Total area of the square field = Area of the path all around the square lawn + Area of the square lawn
⇒ 729 sq m + 295 sq m
= 1024 sq m
So, the area of the square field = 1024 sq m
Length of boundary of square field enclosing the square lawn and the path =
√1024
= 32 m
So, length of the square field enclosing the lawn and the path is 32 m
Width of the path = Length of the boundary enclosing lawn and path - length of the square lawn
⇒ 32 - 27
= 5 m
So, the width of the path is 5 m
