 John anahitaji blanketi mpya. Anachagua kuwa na kitambaa cha ukubwa wa futi 7 kwa futi 8. Kitambaa hicho kina gharama ya $40 kwa futi mraba. Gharama ya kitambaa chake ni kiasi gani?


### Response:
 Kitambaa hicho kina ukubwa wa futi 7 * futi 8 = <<7*8=56>>56 futi mraba
Hivyo, gharama yake ni $40 * 56 = $<<40*56=2240>>2240
