Solutions 


Let the breadth of the rectangular park br represented by = x metres


Therefore, length of the rectangular park be represented by = (x+ 40) meters.


So, area of the rectangular park = (x + 40) ∙ x square meters


According to the problem we get,


(x + 40) ∙ x = 2304


or, x^2 + 40x = 2304


or, x2  + 40x - 2304 = 0 .................... (i)


or we can do 


Let the length of the rectangular park = x metres


Therefore, the breadth of the rectangular park =(x - 40) metres


Area of the rectangular park = x(x - 40) square metres


According to the problem we get,


x(x - 40) = 2304


or,x2  - 40x - 2304 = 0 ....................  (ii)


Both of (i) and (ii) are quadratic equations.
