Answer:
7 in
Step-by-step explanation:
Process of elimination. It can’t be 9 or 10, because 9+9=18 and 10+10=20 (they're more than 16). 8+8=16 exactly, but there’s no room in 16 for the width. Therefore, it’s 7 because 7+7=14
X^2 is x times x, and since x is 2, it's 2 times 2 which equals 4.
The answer is 4.
