anonymous · Answer

a) first of all the map ratio is given by$$Map\ ratio=\frac{length\ on\ map}{actual\ length}$$remember to convert the 1.2km to centimeters which is 120000cm
the answer you will get means $$1cm\ actual\ length\  equals \ the\ answer$$
therefore map ratio is$$1:\ answer(n)$$
b)convert the $$1.6km^{2}\ to\ cm^{2}$$ that is $$1km^2 = 1\times 10^{10}  cm$$ so$$1.6\times1\times10^{10}=1.6\times 10^{10} cm^{2}$$ from the map ratio the area on the map will be $$n \times (1.6\times 10^{10})\ cm^{2}$$
