Is it possible to design a rectangular mango grov

Question

Is it possible to design a rectangular mango grove whose length is twice its breadth, and the area is 800 m2? If so, find its length and breadth.

Dear StudentLet the breadth of mango grove bel.Length of mango grove will be 2l.Area of mango grove = (2l) (l)= 2l^22l^2= 800l^2= 800/2 = 400l^2- 400 =0Comparing the given equation withax^2+bx+c= 0, we geta= 1,b= 0,c= 400As we know, Discriminant =b^2- 4ac=> (0)^2- 4 &times; (1) &times; ( - 400) = 1600Here,b^2-4ac>0Thus, the equation will have real roots.And hence, the desired rectangular mango grove can be designed.l= &plusmn;20As we know, the value of length cannot be negative.Therefore, breadth of mango grove = 20 mLength of mango grove = 2 &times; 20 = 40 mThanks
