That is permuations
that would be 10! or 10*9*8*7*6*5*4*3*2*1=3628800 ways
Recall that

where
is the angle between the vectors
whose magnitudes are
, respectively.
We have


Answer:
Parallelograms I, II, and IV
Step-by-step:
Area of parallelograms:
I. A=3*5=15 units squared
II. A=5*3=15 units squared
III. A=4*4=16 units squared
IV. A=5*3=15 units squared
So, parallelograms I, II, and IV have the same area of 15 units squared.
