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

### Instruction:
Amanda is figuring out how many bags of grass seed she needs to buy to cover a new lot the city is turning into a park. The lot measures 120 feet by 60 feet. One section that measures 40 feet by 40 feet will be covered with concrete, and the rest needs to be covered in grass seeds. Each bag of grass seeds covers 56 square feet. How many bags of grass seeds does Amanda need?

### Response:
 Kwanza, Amanda anahitaji kufahamu ni miguu ngapi za mraba ya eneo ambalo halijafunikwa na zege. Anafanya hivi kwa kuzidisha 120 * 60 = <<120*60=7200>>7200 miguu za mraba.
Kisha, anagundua ni miguu ngapi za mraba inafunikwa na zege kwa kuzidisha 40 * 40 = <<40*40=1600>>1600 miguu za mraba.
Kisha, anatoa miguu za mraba ya eneo la zege kutoka kwenye miguu za mraba ya eneo jumla ili kujua eneo la nyasi: 7200 - 1600 = <<7200-1600=5600>>5600 miguu za mraba.
Hatimaye, anagawanya eneo hili ambalo linahitaji kufunikwa na idadi ya miguu za mraba ambayo kila mfuko unafunika ili kupata idadi ya mifuko: 5600 / 56 = <<5600/56=100>>100 mifuko.
