Answer 2

Step-by-step explanation:

If we have to fence we find the perimeter of rectangular park.

1600÷25=64

64 cm is the perimeter of the rectangular park.

perimeter of rectangle = 2(l+b)

64=2(20+b)

64/2=(20+b)

32-20=b

12=breadth

area of rectangle =l×b

=20×12=240

Breadth of rectangular park is 12cm.

Area of rectangular park is 240 cm sq.
