Answer:
<em>Final velocity, v = 21.75 m/s</em>
Step-by-step explanation:
Given that the relation between final velocity, initial velocity, acceleration and distance traveled is expressed as:

Also, given that:
Initial velocity, u = 9 m/s
Acceleration, a = 7 m/
Distance, s = 28 m
To find:
Final velocity, v = ?
Solution:
The given relation between v, u, a and s is:

We have the values of initial velocity, acceleration and distance traveled in the question statement. We just need to put all these values to find the value of final velocity.
Let us put all the values in the given equation and try to find final velocity, v:

So, the answer is:
<em>final velocity, v = 21.75 m/s</em>
The first three are dependent variables as the outcomes could potentially change due to any of these circumstances.
The last one is an independent variable due to the fact that rolling a die several times will not affect the next outcome.

Answer:
249.6
Step-by-step explanation
There are 4 identical equilateral triangle,
we can find the area of one and multiply by 4
area of triangle = 
now 62.4*4 = 249.6
