How is it possible for $72+96=120$ to be correct?
This is the
side lengths of a right-angled triangle, where the two shorter sides have length 72 and 96; and the longest side has length 120. (Note this is a 3-4-5 Pythagorean triple).
Essentially,
if you travel north 72 units and then east 96 units, it's equivalent to travelling northeast (not exactly, the heading will be $\tan^{-1}\left(\frac{4}{3}\right)$ radians) by 120 units
Answer :
$72^2 + 96^2 = 120^2$
Let's assume
you want to bake a huge apple tart with apples from your own garden. You picked 168 apples (72 + 96) but many of them (96) have turned brown on one side or have a worm, therefore you halve those and throw away the bad halfs. What remains are 120 whole apples (if you count 2 halved apples as 1 whole).
What I want to say is:
72 + 96/2 = 120
