Question

would someone be willing to help me on my last problem? im really stuckkkk!!!!!

Answer 1

Well first let's graph this baby:
(First attachment)
Ok, now to find the distance, you'll need the distance formula:
\[d=\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\]
You'll need to plug in the two points for every side... I know this is tedious, but hey, that's math right?
Anyway, in the second attachment I have all the points labeled and let's start doing this:
Why not start with points A and B?
A(-1, 2) and B(4,4)
now plug it into the distance formula:
\[d=\sqrt{(4+1)^{2}+(4-2)^{2}}\] (remember that two negatives make a positive)
Now we just work it though:
\[d=\sqrt{(5)^{2}+(2)^{2}}\]
\[d=\sqrt{25+4}\]
\[d=\sqrt{29}\]
Now 29 is not a perfect square, so you'll get a decimal. That's ok, round it to the nearest second place. so you get:\[\approx5.39\]
See now this is why I like parallelograms... THEY'RE EQUAL ON ALL SIDES!
For you, this means that every side is going to measure about 5.39. You don't have to find every side, which would have sucked.
So now we just multiply 5.39 by 4 which equals 21.56.
Now to find the area, we do that the same as if we were finding the area of a square. so multiply square 5.39 which equals 29.0521.
That's it!
It's a parallelogram, or an equilateral parallelogram (which means everything is equal)
Perimeter = 21.56
Area = 29.0521

Be sure to work though it on your own so you really get it.
Good luck!
