You can divide equally when you group the 3 different sides of the rhombuses into a set.

The question asks for the perimeter of the figure. You included all 4 sides of each rhombus in your working.
The inner side is sandwiched by the triangle so it's no longer part of the outline of the figure and thus it cannot be included in the perimeter.
You should only be counting 3 sides of each rhombus.
