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

### Instruction:
Henrietta is repainting her house. The walls in the living room take up 600 square feet. She has three bedrooms. The walls in each bedroom take up 400 square feet. If one gallon of paint can cover 600 square feet, how many gallons of paint does Henrietta need to paint her house?

### Response:
 Jumla ya eneo la futi za mraba kwa vyumba vitatu ni 3 * futi za mraba 400 = <<3*400=1200>>1200 futi za mraba.
Jumla ya eneo la futi za mraba la nyumba ni 1200 + 600 = <<1200+600=1800>>1800 futi za mraba.
Henrietta anahitaji futi za mraba 1800 / futi za mraba 600 = <<1800/600=3>>3 galoni za rangi ili kupaka nyumba yake.
