map A
map : real field
1cm : 2.4m
square whole thing to get area,
1cm^2 : 5.76m^2
x25 to both sides,
25cm^2 : 144m^2
since they say area of MAP B is 2.56x bigger ,
x 2.56 to both sides,
64cm^2 : 368.64m^2
the question wants the Real Field of map B.
means the unit is metre(m)
so just square root both sides!
8cm:19.2m
answer is 19.2m
