    OK, looks like what you need is to calculate the distance between each of the two points. So, for example, we need to find the distance between Q(2,0) and R(4,5).

    so I would use the distance formula?

    If you are familiar with that formula, yes!

    I prefer this version, but you can use whatever you are most comfortable with: d = square root( (difference in x's)^2 + (difference in y's)^2 )

    Thank you! I will work it out and then show you my answer, is it okay if I tag you in it? and then if I post the next question can I tag you? I only have 1 more:)

    Sure! Remember for this one that you will need the distance for each of the edges all the way around the figure. :)

    so when I find the distance for each edge then what do I need to do?

    Once you find each distance (there should be 5) the perimeter is just the total of them added up.
