the seats at a local baseball stadium are arranged so that each row has 5 more seats than the row below it. if there are 4 seats
Dvinal [7]
The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,                                          an = a1 + (n - 1) d
Solving for the 23rd term,                                            an  = 4 + (22) 5 = 114 seats
Therefore, the answer is there are 114 seats on the 23rd row.

How to find area of parallelogram with coordinates of verticles?
ExtremeBDS [4]
You find a parallelogram area by this formula:
A=b\cdot h
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
A(x_1,y_1)\;\;\;\;B(x_2,y_2) \\  \\ 
d_{AB}= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} =b

And h is the perpendicular distance between both bases.
You can visit next link to know further about it:

And in attached picture you can find an example in progress you may want to finish.
