In a rectangle, the one side is always longer than the other.
We mark "x"= height.
And the other side is 2m longer than this, so "x+2m"=the longer side (accdg. to your problem is the width).
Since we have a brace of , go by Pyth. Theorem to solve the other sides.

Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=8 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 0.414213562373095, -2.41421356237309. Here's your graph:
