Question

Barbara is drawing a square whose lengths are increasing in a pattern as follows:

What will be the length of the sides of the last square?

• A. 100 units
• B. 65 units
• C. 108 units
• D. 85 units

Answer 1

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 $\times$ 3 = 12
12 $\times$ 3 = 36


So the length of side of the last square will be
36 $\times$ 3 = 108 units
