S1 (Viva Voce) Part A Question 1

Q2) i)
Triangle = (2x+1) X 4   =  8x + 4   =   4x + 2 cm²
                        2                   2
Parallelogram 
= 2(2x + 1) X 2
= (4x + 2) X 2
= 8x + 4 cm²
Finding X
= (8x + 4 ) - (4x + 2) = 10cm
= 8x + 4 - 4x - 2 = 10cm
= 4x - 2 - 10cm
= 4x = 12cm
x = 3cm
Finding area of triangle
(2 X 3 +1) X 4   =   7 X 4   =  28  = 14cm²
       2                         2           2

ii) 14cm² ÷ 100
= 0.14
0.14 ÷ 100
= 0.0014m²


S1 (Viva Voce) Part B Reflection


The challenges I faced was that, when recording the screenrecording. I messed up on my first couple of tries and had to redo them. Another thing was background noise so I had to ask my family to keep quiet while i did the recording.
