Mr Chiang oh dear sir.
Since the past few weeks, I have not understand one bit about your lessons.
So give me extra lessons, or I will fail CT1.

#1 How do I find the dimensions of my school court?

1. Take a measuring tape.
2. Measure the length and breadth of the court.
3. If the tape is not long enough to measure the whole of the court, mark on where your tape stopped.
4. Find the area by multiplying the length and breadth.
5. Use a ratio to draw a map to scale. [ I used 0.5cm : 1m ]
6. Find the map area by multiplying the map length and map breadth.
7. Find the court to map ratio LxB(Badminton Court) : LxB(Map Cm)

Somehow, my friend's measuring tape got stuck because it was too rusty, and we had to throw the measuring tape.
