All integer numbers are either even or odd. So, the complement to the set B (to the set of all even integers) is the set of all odd integers, that is D.
The integer number of the form 2x is always even, because it is always divided by 2, so the set C is the empty set.
Numbers 1, 3, 5, 7 are odd, therefore they belong to the set D.
Using the Pythagorean theorm,
a^2 + b^2 = C^2, where a nd b are the side lengths and c is the hypotenuse ( diagonal line)
If it was a square both sides would be the same length so we would have:
13^2 +13^2 = c^2
169 + 169 = c^2
338 = c^2
c = SQRT(338) = 18.38
18.38 is larger than the 15.26 given in the problem , so the room is not a square.
