Hello! I have got a weird question regarding estimation.
Say a question requires us to estimate the area of a place (eg.
land area of an average secondary school), how do we typically go
and find out the area? I was told to use google and find the area
by counting the no. of grids and multiply accordingly to the scale
of map. But I tried to google for maps of school area but the maps
all don't give you a rough scale.
Can someone help? Just give me the link and advise me on the
scale. (this is urgent!) thanks so much
