1. Fencing is done around the perimeter.
2. Perimeter of rectangle:2(l+b), where l: length and b: breadth of rectangle.

Step 1:

Find the perimeter of rectangular park.

As,

Length (l)= 250 m and Breadth(b)= 175 m

Thus,

$\text{Perimeter} = 2(250 + 175)$

or

$\text{Perimeter} = 2(425)$

or

$\bold{\text{Perimeter} =850 \: m}$

Step 2:
