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

### Instruction:
James is building a hall of mirrors. Three of the walls will be completed covered with glass. If two of those walls are 30 feet by 12 feet and the third is 20 feet by 12 feet, how many square feet of glass does he need?

### Response:
 Kwanza tafuta eneo la kila ukuta mrefu: futi 30 * futi 12 = <<30*12=360>>360 eneo la futi za mraba
Kisha fanya hivyo hivyo kwa ukuta mfupi: futi 20 * futi 12 = <<20*12=240>>240 eneo la futi za mraba
Sasa ongeza eneo la kuta zote mbili ndefu kupata eneo jumla la kuta: 360 eneo la futi za mraba + 360 eneo la futi za mraba = <<360+360=720>>720 eneo la futi za mraba
Sasa ongeza eneo la ukuta mfupi kupata eneo jumla la kuta: 720 eneo la futi za mraba + 240 eneo la futi za mraba = <<720+240=960>>960 eneo la futi za mraba
