Formula for the area of a square = side^2
So, 15^2 will result in the area.
Thus, the answer is 225 mm^2 (when squaring, units are always given the square as well.)
Answer:
31.205

The perimeter is the sum of the side lengths:
8.73 +12.4 +10.075 = 31.205
_____
If you're after an answer that has the appropriate precision (assuming these are measured values), that would be one that is rounded to 1 decimal place: 31.2.
The answer would be C) The volume is the same in both cylinders
