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

### Instruction:
Martha needs to paint all four walls in her 12 foot by 16 foot kitchen, which has 10 foot high ceilings. Each wall needs one coat of primer and two coats of paint. If Martha can paint 40 square feet per hour, how many hours will it take her to paint the kitchen?

### Response:
 Kuna kuta mbili zenye ukubwa wa 12' x 10' na kuta mbili zenye ukubwa wa 16' x 10'. Kwanza, tafuta ukubwa wa eneo la futi za mraba la ukuta mmoja wa 12' x 10' kwa kuzidisha urefu na upana: 12 ft * 10 ft = <<12*10=120>>120 futi za mraba
Zidisha kiasi hicho mara 2 kwa kuwa kuna kuta mbili za 12' x 10': 120 futi za mraba * 2 = <<120*2=240>>240 futi za mraba
Kisha tafuta ukubwa wa eneo la futi za mraba la ukuta mmoja wa 16' x 10' kwa kuzidisha urefu na upana: 16 ft * 10 ft = <<16*10=160>>160 futi za mraba
Zidisha kiasi hicho mara 2 kwa kuwa kuna kuta mbili za 16' x 10': 160 futi za mraba * 2 = <<160*2=320>>320 futi za mraba
Sasa ongeza eneo la futi za mraba la makundi yote ya kuta ili kupata jumla ya eneo la futi za mraba ambalo Martha anahitaji kupaka: 240 futi za mraba + 320 futi za mraba = <<240+320=560>>560 futi za mraba
Sasa zidisha kiasi hicho mara 3 kwa kuwa Martha anahitaji kuongeza safu 3: 560 futi za mraba/safu * 3 safu = <<560*3=1680>>1680 futi za mraba
Hatimaye, ugawanye jumla ya eneo la futi za mraba na kasi ya kupaka rangi ya Martha ili kupata saa ngapi anahitaji kumaliza: 1680 futi za mraba / 40 futi za mraba/saa = <<1680/40=42>>42 saa
