Given that perimeter of a rectangular field = 180m.

2(l + b) = 180

(l + b) =  \frac{180}{2}

(l + b) = 90

l = 90 - b   ------------ (1).


Given that Area of rectangular field = 20000m.

l * b = 20000

(90 - b) * b = 20000

90b - b^2 - 20000 = 0

b = 45 + 5i \sqrt{719} , b = 45 - 5i \sqrt{719} .


Note: kindly check the question once again.
