Hello! I have a question for number 7. I completely understand your method of approach..but I was wondering, to find the area of this large triangle (which is right-angled), couldn't I find the area by taking the base as GI (p+6), the height as KI (q+8)...which would give me 0.5(p+6)(q+8)...would this also be correct?

Hi! for question 6, why isnt the rounding for the side 56.49 and 82.49? I though when a number had .5 it was rounded up?
