Answer:
42 units squared
Step-by-step explanation:
break it up into smaller shapes. if you split the big shape at y = 2 and at y=-2, you'll get two triangles and one rectangle.
so the area of the rectangle = l x w
= 4 x 7
= 28
the area of the triangle is ( l x w )/2
= (7 x 2)/2
= 7
the other triangle is the same too
so the area of that is also 7.
now add all areas,
7+7+28 = 42

The answer is

----------------------------------------------------------------------------------------------
Explanation:
The first term is

. The next part of the rule, which says

is the recursive part. To get the nth term, we add on 4 to the previous (n-1) term. For example, to get the fifth term, you add on 4 to the fourth term. Relying solely on this recursive definition means we need to find all of the previous terms (from 1 to n-1) in order to find a given nth term.
By comparing the right triangle ABC with the triangle XYZ, we will see that:

So we know that the largest triangle is a dilation of scale factor 2 of the smaller one.
Also, remember that for right triangle we have the relation:
Tan(θ) = (opposite cathetus)/(adjacent cathetus).
Now, the problem tells us that:
tan(x) = 5/2.5
For the angle x, the adjacent cathetus is XY, and the opposite cathetus is YZ.
Then we have:
YZ = 5
XY = 2.5
Knowing that the correspondent sides in the larger triangle will be 2 times the above ones, we can see that:
AC = 2*XY = 2*2.5 = 5
CB = 2*YZ = 2*5 = 10
