Answer:
Step-by-step explanation:
The formula of an area of a trapezoid:
<em>b₁, b₂</em> - <em>bases</em>
<em>h</em><em> - height</em>
We must use the Pythagorean theorem:
<em>subtract 64 from both sides</em>
We have <em>b₁ = 6 + 6 = 12m</em>, <em>b₂ = 6m</em> and <em>h = 8m</em>.
Substitute:
Answer:
I = 3\8 . F and F = 8\3 . I
Step-by-step explanation:

Total number of team in starting = 128 teams.
In each round half of the teams are eliminated.
Therefore, number of teams remain after first round = 128/2 = 64.
The number of teams remain after second round = 64/2 = 32.
The number of teams remain after third round = 32/2 = 16.
The number of teams remain after fourth round = 16/2 = 8.
The number of teams remain after fifth round = 8/2 = 4.
<h3>Therefore, after 5 rounds there remain only 4 teams.</h3>
The answer is B, you should really learn how to calculate these yourself though because they come up a lot.
