Question

Find the perimeter of trapezoid KLMN

Answer 1

perimeter = sum of length of all sides

Answer 2

They have angles, L (-1,6), M (4,1), K (-2,1), N (0,-1)

Answer 3

And its a multiple question.
\[2\sqrt{26}\]
21
104
\[7\sqrt{2}+2\sqrt{5}+\sqrt{26}\]

Answer 4

find the length of all sides and add them up

Answer 5

Those angles are x, y co-ordinates right?
I just made a quick attempt at a graphic and it seems to me that only 2 points are on the same y value.
Then again, I guess they wouldn't need the same x or y values if the sides run diagonally,
For example, are the parallel sides LM and KN?

Answer 6

@angel32412 tell me how you get it through their angles ?

Answer 7

@einsteinmorse What do you mean?

Answer 8

\(\bf \text{distance between 2 points}\\
d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\)

Answer 9

@jdoe0001 So Just put in two of the points into the formula and do it again for the next two and add them up and voila, I get my answer?

Answer 10

yes

Answer 11

How did u get Those points

Answer 12

@EinsteinMorse it just says it on the paper I got here.

Answer 13

Its awesome that's why I loved math

Answer 14

How did u use angle degrees to get those points

Answer 15

I know Distance between two points but its kinda awesome how did you get ur answer

Answer 16

@angel32412 pls tell it to me ?

Answer 17

@EinsteinMorse sorry I had to do a couple of things

Answer 18

L (-1,6), M (4,1), K (-2,1), N (0,-1)

Answer 19

@EinsteinMorse hey I got two answers that dont make senese

Answer 20

@Einstienmorse \[\sqrt{34} and \sqrt{2}\]

Answer 21

Figured I'd make another graphic (drawn a lot better).
Hope this helps.

Answer 22

@wolf1728 I got that, but I dont understand how to solve it. They give me four multiple choice answer I just cant figure out what is what and how to do it

Answer 23

angel I believe I have the lengths of all 4 sides:
7.0711 LM
5.099 KL
2.8284 KN
4.4721 NM

19.4706 Perimeter
The sides were found by the Pythagorean Theorem.
By the way, I hope 19.4706 is one of the choices.

Answer 24

@wolf1728 you are the bomb! You got it. Thank you so much!

Answer 25

All right - and you can print out the graphic to go along with your answer.
(I never ask for a medal but considering I made a graphic - than another one - then I had to do those Pythagorean calculations ... but feel free to do as you wish.
