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

### Instruction:
 Baada ya somo la jiometria, Bill anataka kuhesabu idadi ya mistari aliyoichora. Kwa kila umbo, aliichora mstari mmoja kwa kila upande. Ikiwa aliichora pembetatu 12, mraba 8, na pentagoni 4, alichora mistari mingapi?


### Response:
 Kwa pembetatu, aliichora mistari 36 kwa sababu 12 x 3 = <<12*3=36>>36.
Kwa mraba, aliichora mistari 32 kwa sababu 8 x 4 = <<8*4=32>>32.
Kwa pentagoni, aliichora mistari 20 kwa sababu 4 x 5 = <<4*5=20>>20.
Jumla ya mistari aliyoichora ni 88 kwa sababu 36 + 32 + 20 = <<36+32+20=88>>88.
