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

### Instruction:
After geometry class, Bill wants to count how many lines he drew. For each shape, he drew one line per side. If he drew 12 triangles, 8 squares, and 4 pentagons, how many lines did he draw?

### 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.
