String in yaml

Configuration
1

{states[‘sensor.skoda_octavia_combi_elektrische_reichweite’].state}

This is a yaml config I used in a mushroom template card. How can I add string to the code so it shows “‘state’ km”?

Thanks in Advance

{{states ('sensor.skoda_octavia_combi_elektrische_reichweite') + " km"}}
