Find the perimeter of the polygon with the given vertices

g(2,4), h(2,-3), j(-2,-3), k(-2,4)

I graphed these vertices myself in the attached photo, and it turned out to be a rectangle;  With the thought that you perhaps made a typo and meant rectangle instead of polygon I continued on and found the perimeter of the rectangle.  

The formula for finding the perimeter of a rectangle is P = 2(l+w).  

I counted the units of the long side (K & J) to get the length, which is 7.

Next, I counted the units between J & H to find the width which is 4.  Now we're ready to use the formula.  

First I will add the length plus the width, 7 + 4 = 11.  

Then I will multiply 2 x 11 to get a product of 22.  

P = 22.  :D 

The correct answer will be d. -4
