Answer 1

do you know the formula to find the distance between 2 points ?

Answer 2

Yes, I do, but I'm unsure on how that will help to find the perimeter.

Answer 3

the perimeter is the sum of the lengths of all 3 sides
so you need to find three lengths. then add them up

Answer 4

use the pythagorean therom; a^2+b^2=c^2

Answer 5

4+4+sqrt(3)

Answer 6

srt(32)

Answer 7

they made a mistake when they put b's coordinates in, it should be -3 not 3 xD

Answer 8

btw, there is a typo in point B, it is at (-3,2) (NOT (3,2) as shown)

Answer 9

I think I have the wrong formula. How do I plug three of them in when the formula is only made for 2 set of points. & Yes I know there is a typo. Sorry, I forgot to mention that.

Answer 10

of course, you can just count how many "steps" it takes to move from point B to point C, which is easier than using the distance formula
same for the distance from point B to point A

Answer 11

you get 17.21 as your answer when you add the sides up.

Answer 12

well actually 17.2111025509 but it said round to the nearest 100th

Answer 13

I didn't really want the answer @trantom I just wanted help on how to solve it.
Thank you Phi, I think I've got it. I really appreciate it. :)

Answer 14

I told you the pythagorean therom!

Answer 15

thats how you solve it!
