Finding the critical buckling load of a really short column with wide cross section (is it still considered a column?)

E = 22 GPa

Yield: 300 MPa

Load: 28N

thickness: 0.226 mm

I = 670706.51 mm^4 (is this right?)

Load Applied Area (as indicated by white arrows): 190400 mmÂ²

I understand from http://www.engineersedge.com/column_buckling/column_ideal.htm that I should be applying Johnson's Formula.

2. Relevant equations

Johnson's Formula

3. The attempt at a solution

Using Johnson's formula, I've found out the Critical Buckling Load (Pcr) is 57119986 N

I know this is a really short structure with a wide cross sectional area so naturally the Pcr will be bigger but could someone please verify my method?
