Solution

To find the cost we need to find the perimeter of the triangular park
The perimeter of the Triangular park $= S u m o f e a c h s i d e s$
$= 35 + 54 + 67 = 156 m$
Length need for fencing $=$ $p e r i m e t e r o f p a r k - 3 \times l e n g t h o f g a t e$
$= 156 - 3 \times 2.5 = 156 - 7.5 = 148.5 m$
The cost of fencing $= t o t a l l e n g t h \times r a t e o f f e n c i n g$
$= 148.5 \times 7 = ₹ 1039.5$
Hence the cost of fencing is $₹ 1039.5$ .
