Rails, how to link to another static page within my domain.

I have such as: (this is home page.)

```
<%= link_to image_tag("rails.png", alt: "Rails"), 'www.goole.com' %>

```

instead of link\_to google. I want it link to "contact" static page.
What should I put there?

my routes.rb is this:

```
SampleApp::Application.routes.draw do
  get "users/new"
  # get "static_pages/home"
  # get "static_pages/help"
  # get "static_pages/about"
  # get "static_pages/contact"
  root 'static_pages#home'
  match '/signup',  to: 'users#new',            via: 'get'
  match '/help',    to: 'static_pages#help',    via: 'get'
  match '/about',   to: 'static_pages#about',   via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get'

```
