RE: Little explorations with the HP calculators
It would be nice if there was a feature to hide parts of a post until a user explicitly clicks a spoiler button. Anyway draw a line through E and parallel to AB. Let G be the point of intersection of this line with BC and note G is the midpoint of BC. EGC has area 1/4*24=6. Note that EG has length 1.5y. Hence ADE has area 4. BDF has half the height as ADE (a second line through F parallel to AB helps to see this) but twice the base length. Therefore its area is also 4. Lastly EFG (compared vs BDF) has area 3 using a ratio of their bases.
