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
Please post the full question.
Anyway, you could try gothere.sg
The scales are given there I believe
just do alot , ALOT of assumptions~ but assumptions should be reasonable.
