[Haskell-beginners] is this not a better way ? data structure

In the book there is a example of this data-structure.

data Shape = Circle float float
                      | Rectangle float float

Now I have to change it to add a center point.

But I wonder if this is not a better way to describe it

Data Schape = Circle Radius
                     | Rectangle Width Height

Type Radius = Float
type Width = Float
type Height = Float
