Maths Performances Task By Choy Rui Zhi **Updated**

Part 1 
\
(i)2x + 3 = 3x - 7 (length)

         + 7         + 7 =
    2x + 10 = 3x
    -2x           -2x  
   10 = x 
Thus x = 10cm
(ii)(2x+3) = 2 x 10 + 3 = 23
    (4x-30) = 4 x 10 - 30 = 10
     23 x 10 = 230 

Thus the area is 230cm^2

(iii)convert cm^2 to m^2 
      1m = 100cm 
       230cm^2   (2 times)
      
       230 ÷ 100 = 2.3
       2.3 ÷ 100 = 0.023m^2
Thus the answer is 0.023m^2


NOTICE***Sorry,  but the same problem as last time the video is blur at first. Any one have any idea to make that disappear***


Part 2-Reflections
Basically, the problem i faced is the use of correct terms to explain my solution. The question i chose was easy to do but hard to explain. I tried my best to pronoun the correct terms. This experience also helps me to learn to express the correct term and it also can use my creativity to express my solution.I think that i can improve on the words i say. In my opinion , posting your own answers and their own way of expressing the terms in the blog for people to see can be useful as everyone can learn from each other and learn from their own mistakes.
