Question B
Firstly, I noticed that the three horizontal rectangles were smaller than the two vertical ones. I did trial and error to figure this question out. I figured out that the area of all the horizontal rectangles would add up to thirty and the same with the vertical rectangles. I first tried 10cm2 per horizontal rectangle (10x3=30)and 15cm2 per vertical rectangle (15x2=30). This all adds up to thirty and I decided that that was the best answer.
