Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Brashi ya Carla ina urefu wa inchi 12. Ikiwa brashi ya Carmen ni 50% ndefu kuliko brashi ya Carla, urefu wa brashi ya Carmen ni sentimita ngapi? (Kuna sentimita 2.5 kwa inchi.)


### Response:
 Kwanza tafuta urefu wa brashi ya Carmen kwa inchi: 150% * inchi 12 = <<150*.01*12=18>>18 inchi
Kisha badilisha urefu huo kutoka inchi kwenda sentimita: inchi 18 * sentimita 2.5/inchi = <<18*2.5=45>>45 sentimita
