Solution
The correct option is C 108 units Looking at the the pattern closely, we get:
The consecutive length of the next square in the pattern are formed by multiplying 3 with the length of the previous square.
We see:
4 × 3 = 12
12 × 3 = 36
So the length of side of the last square will be
36 × 3 = 108 units
