Is it possible to design a rectangular park of perimeter 80 m and area 400 m2? If so, find its length and breadth.

Explanation

To determine if it is possible to design a rectangular park with a perimeter of 80 meters and an area of 400 m², we can follow these steps:

### Step 1: Set up the equations for perimeter and area.
The perimeter \( P \) of a rectangle is given by the formula:
\[ P = 2(L + B) \]
where \( L \) is the length and \( B \) is the breadth. Given that the perimeter is 80 meters, we can write:
