Is it possible to design a rectangular park of perimeter 80 m and area 400 m^(2) ? If so, find its length and breadth. Comment on you answer.

Is it possible to design a rectangular mango grove whose length is twice its breadth, and the area is 800 m^(2) ? If so, find its length and breadth.

A rectangular park is to be designed whose breadth is 3 m less than its length. Its area is to be 4 square metres more than the area of a park that has already been made in the shape of an isosceles triangle with its base as the breadth of the rectangular park and of altitude 12 m. Find its length and breadth.

The least possible perimeter of a rectangule of area 400 m^(2) is
