8 – What is the route in my myModule.routing.yml for myModule.module?

I built my module called myModule with Webforms module.
myModule is defined in webmodulecustommymodule

I introduced some forms (myModuleHeightCalculation, myModuleWidthCalculation…) and defined their route in myModule.routing.yml (see below).
These forms are called from myModule.module in mymodule_from_alter.

Currently, I’m able to compute the surface and display it in a new form myModuleSurfaceResult.
But, I want to display this result in MyModule webform.

What is the route for myModule in myModule.routing.yml?

See below my myModule.routing.yml file:

myModule.height_calculation:
  path: '/myModule-height-calculation'
  defaults:
    _title: 'Height calculation'
    _form: 'DrupalmyModuleFormmyModuleHeightCalculation'
  requirements:
    _role: 'authenticated+administrator'
myModule.width_calculation:
  path: '/myModule-width-calculation'
  defaults:
    _title: 'Width calculation'
    _form: 'DrupalmyModuleFormmyModuleWidthCalculation'
  requirements:
    _role: 'authenticated+administrator'
myModule.surface.result:
  path: '/surface-result/{result}'
  defaults:
    _title: 'Result'
    _form: 'DrupalmyModuleFormmyModuleSurfaceResult::content'
    result: ''
  requirements:
    _role: 'authenticated+administrator'
