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

### Instruction:
 Jazel ana vijiti 3. Kijiti kimoja kina urefu wa sentimita 3. Kijiti cha pili kina urefu mara mbili ya hicho wakati kijiti cha tatu kina urefu wa sentimita 1 chini ya kijiti cha pili. Urefu jumla wa vijiti vya Jazel ni upi wanapowekwa pamoja?


### Response:
 Kwa kuwa kijiti cha pili kina urefu mara mbili ya kijiti cha kwanza, basi kina urefu wa sentimita 2 x 3 = <<2*3=6>>6.
Kijiti cha tatu kina urefu wa sentimita 6 - 1 = <<6-1=5>>5.
Hivyo, vijiti vya Jazel vina urefu wa sentimita 3 + 6 + 5 = <<3+6+5=14>>14 wanapowekwa pamoja.
