### Instruction:
 Sakafu ya umbo la mraba yenye urefu wa mita 10 na upana wa mita 8 inatarajiwa kufunikwa na zulia lenye umbo la mraba lenye upande wa mita 4. Ni eneo mangapi ya sakafu hayajafunikwa?


### Response:
 10 m x 8 m = <<10*8=80>>80 mita za mraba
4 m x 4 m = <<4*4=16>>16 mita za mraba
80 mita za mraba - 16 mita za mraba = <<80-16=64>>64 mita za mraba
64 mita za mraba = <<64=64>>64
