Answer:
Option B.
Step-by-step explanation:
It is given that
A = {The Rationals}
B = {The Irrationals}
We need to find the set A∪B.
If we have two sets X and Y then union of these sets (X∪Y) contains all the elements of set X, of set Y or both.
It is given that A is the set of rations and B is the set of irrational, so the union A∪B is the combined set of all rational or irrational numbers.
A∪B = {The Rationals} + {The Irrationals}
A∪B = {The Reals}
Therefore, the correct option is B.

Answer:
400 in^2
Step-by-step explanation:
A square has equal sides, s and the area = s * s
volume of refrigerator = s *s * h
= s^2 * 40 = 16000
s^2 = 400
s = 20 inches so area = 20 * 20 = 400 in^2
