x = length of original side
x-8 = length of side which had 4 trimmed from each edge
x-10 = length side which had 5 trimmed from each edge

area left = 120
so
(x-8)(x-10) = 120
x^2-18x+80 = 120
x^2-18x-40 = 0
(x-20)(x+2)
hence x = 20 and x = -2
can't have a negative side
so
x=20

check answer:
(20-8)(20-10)
(12)(10) = 120

I believe this is correct, but couldn't find it in the OG
