Answer:
21
Step-by-step explanation:
the formula for a triangle is A=1/2bh
so u multiply the base times the height then get 42. if u multiply anything by 1/2 or .5 its the same thing as dividing. so you divide 42 by 2 and get 21.
There are 11 elements are in (A U B)
<h3>How to determine the number of elements?</h3>
The given parameters are:
n(A) = 4
n(B) = 7
The number of elements in (A U B) is calculated using:
n(A U B) = n(A) +n(B) - n(A U B)
Given that the sets have distincts elements, we have:
n(A U B) = 4 + 7 - 0
Evaluate
n(A U B) = 11
Hence, there are 11 elements are in (A U B)
