Answer:
answer you get is :l=20,b=20
Step-by-step explanation:
perimeter of rectangle= l+b+l+b
area of rectangle=l*b
hence, 2l+2b=80.....(1)
l*b=400
b=400/l(substitute this in equation 1)
you get a quadratic equation solve it
from this you get answer: l=20,b=20...so can see that both sides are equal only square park can be formed....hence rectangle park cannot be formed.
