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

### Instruction:
Joyce moved to the countryside because she needed more farmland to grow her vegetables.  Her new property is 10 times larger than her previous property, but her new land has a 1-acre pond on it where she cannot grow vegetables.  If her previous property was 2 acres, how many acres of land does she now own that are suitable for growing vegetables?

### Response:
 Ardhi mpya ya Joyce ni mara 10 kubwa kuliko mali yake ya zamani ya ekari 2, kwa jumla ya ekari 10*2=<<10*2=20>>20 za ardhi.
Ekari 1 haiwezi kutumiwa kwa kilimo, hivyo anabakiwa na ekari 20-1=<<20-1=19>>19 za ardhi zinazofaa kwa kilimo.
