We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

How to get the sum of the first 8 terms?</h3>
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:

There are 7 times the common difference between these two values, so if d is the common difference:

Then the sum of the first 8 terms is given by:

So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

Just find the base area then multiply it by the height. 
so here for the base area we can divide it in 2 parts 6x6 + 2x1
which the total is 38 
then multiply 38 by 1, which is the height, so it's 38
