Q1. The map of Jurong Bird Park has a scale of 1 : 3000.
(a) If the length from the entrance to Flamingo Gardens is 4.5cm on the map, calculate the actual distance, in km.
(b) The actual area of the Parrot Enclosure is 0.0225km^2.
Calculate the area on the map that represents the enclosure, giving your answer in square centimeters.
Q2. A nature reserve of area 225km^2 is represented on a map by an area of 36cm^2. Find the R.F. of the map. What will be the area of the nature reserve be on another map whose scale is 1cm to 5km.
Q3.On a map, a road 4.8km long measures 12cm. Find
(a) the scale used in the form of R.F.
(b) the actual area of a field which measures 28cm^2 on the map.
(c) the area, in cm^2, of the same field on a second map whose scale is 1:20000.
Thanks in advance..
Test came out and got this 3 wrong..we're suppose to do our own corrections. But I still don't get what my teacher is saying. So please help..
With ur steps,, try to explain why too.. thanks..
Answer :
Q1. The scale is 1:3000 means 1cm is 3000 cm ,i.e., 1cm is 30 m
a) 4.5 cm on map means (4.5 * 30) m actually, now 4.5 * 30 = 225 m = 0.225 km
Hence answer should be 0.225 km
b) 0.0225km^2 means it should be a square region with length 0.15 km ,i.e., 150m, so according to the scale the length of the enclosure on the map should be 5cm.
Hence the area on the map will be 25cm^2.
Q2. 225km^2 means a square with the length as 15km and 36cm^2 means a square with the length 6cm. Hence the scale is 6cm is 15km, so 1cm is 2.5km means 1:250000.
On another map 1cm is 5km, so 15km will be 3cm. Hence the area of the nature reserve on another map will be 9cm^2.
Q3. 4.8km is 12cm, hence scale is 1cm is 0.4km or 400 m
(a) 1cm is 400 m so 1:40000
(b) 1cm is 400 m, so 1cm^2 will be 160000m^2 or 0.16km^2
So 28cm^2 is 28 * 0.16 = 4.48 km^2.
(c) 1:20000 means 1 cm is 0.2 km so 1cm^2 is 0.04km^2.
hence on another map the area will be 4.48/0.04 = 112cm^2

What is better: Singapore Zoo, Night Safari or Jurong Bird Park??
For a family with 2 kids aged 12 nd 14.
Just out of curiousity if we had to pick one place out of those three, which one would it be??
Answer :
Well my dear... All these 3 places are definitely worth going :)
However you may wish to start with the Singapore Zoo. It would definitely be both an educational and enjoyable trip for your kids especially.
They will definitely appreciate the huge conservation efforts by the zoo in protecting and preserving the wildlife and the endangered species, eg, the polar bears, orang utan....
Try and go to the zoo in the morning (say about 9 am) where the animals are at their most active. Most of them would be asleep in the afternoon and sometimes it would be difficult to see them if they are sleeping in a hidden corner of their enclosure.
If you are taking public transportation, take the mrt to Ang Mo Kio station. Then take bus 135 from AMK hub. The bus will bring you directly to the zoo's entrance.
Enjoy your trip!
Answer :
I would definitely suggest you pick the zoo. It is a world renown zoo. Many people who have visited the zoo have given it rave reviews. With regards to the Night Safari, I personally say that there is nothing to see as it is all 'black' (meaning it's dark). As for the Jurong Bird Park, unless you are a true bird fan, it's all bird species only.
Answer :
well i promise you going to the night safari is not very good. i went there with my grandparents and the were literally over 2000 people lined up for these little car like things that take you around the park and you cannot see a thing and no flash on a camera is aloud so you cant get pictures. For us, we all hated it, but the singapore zoo, i suggest you go there because it has alot of animals.
(i was 13 at the time, now im 14)
Answer :
go to the Zoo.
Night Safari you can't see a thing. we enjoyed the tram but you have to wait a while since lots of people waiting to take the ride also.
bird park so so...

What Species of Parrot is This?
I took this photo at Jurong Bird Park of two small parrots feeding each other. Here's the photo: http://img.photobucket.com/albums/v691/C…
What I assume to be the male is green with red on his face and chest(?). He has a blue cheek patch.
What I assume to be the female is green with yellow cheek patches and yellow chest.
Anyone know what species this is? Thanks for your help. :)
Answer :
It looks like a Rainbow Lorikeet.

I found it! lol!
Red-flanked Lorikeet:

Do the following French sentences make sense? If not, how should I improve them?
Je suis dans Singapore pour une semaine de vacances d’été. Voici quelques photos pour vous pour regarder. J’adore cet endroit ! Il y a beaucoup de choses à faire et de beaucoup de choses à regarder ; c’est très fun! Il ne y a pas les quatre saisons ici. Quand il fait frais, les gens vont au zoo ou au parc d’oiseau. On fait du shopping et sortir à le cinéma ou à le parc d’attractions. Ma famille et moi, nous allés au Singapore Zoo, Jurong Bird Park, Sentosa Island, Singapore Flyer, et Singapore Discovery Center. J'ai un temps génial! Je veux à vivre dans Singapore parce que il est très sympa !
Answer :
Never use dans to say you in a country "en" with feminine countries.. "à" with cities.
Your using POUR incorrectly .

http://french.about.com/library/preposit…
Why are you using the English word "FUN"
Il n'y a pas..... correct your negation
You cannot say à le parc -- au parc nor à le cinéma - au cinéma
Vouloir (to want) does not require a preposition when followed by a verb
veux vivre is the correct structure
All in all, you did rather well on your work..
there are a couple of other mistakes I did not address
Answer :
je suis EN singapore DEPUIS une semaine pour LES vacances d'été.
Il y a beaucoup d'activités à faire et bien de choses à regarder ; c'est très amusant! Il n'y a pas....
On fait du shopping et sortir au cinéma ou au parc d'attractions. Ma famille et moi, nous sommes allés... C'était génial! Je veux habiter en Singapore parce qu'il est trés agréable.
