A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88

Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88

12 x


so it is
if you had
 a b
 c d x
 (ad)(bd)
(bc)(ac) +
result

first you do
2 times 4 then place it below the 2

14
12 x
 8

then you do 2 times 1 then place it below

14
12 x
28

then you move on the the one

1 times 4

14
12 x
28
4

then 1 times 1

 14
 12 x
 28
14
