Which of the following sets represent A ∪ B? {6, 12} {2, 3, 4, 6, 8, 9, 10, 12} {1, 5, 7, 11} {2, 3, 4, 8, 9, 10}

Solution:

The complete figure of question is attached below

From figure,

Write all elements from set A

A = {3, 6, 9, 12}

Write all elements from set B

B = {2, 4, 6, 8, 10, 12}

AUB means A union B

AUB means set of all the numbers combined with set A and set B

Combine set A and B

AUB = { 2, 3, 4, 6, 8, 9, 10, 12}

Thus AUB is found

the answer is 48m^2!
