Question

A triangle is graphed in the coordinate plane. The verticals of the triangle have (-4,1), (1,1), and (1, -11). What is the perimeter?

Answer 1

you're gonna have to do distance formula thrice =_= that's a toil

Answer 2

use the distance formula 3 times

Answer 3

wats the distance formula. i dont get this someone's goin to have to explain it to me

Answer 4

distance formula is d=sqrt( (xf-xi)^2+ (yf-yi)^2)

Answer 5

the f and i just means initial and final.

here is a hint. If you got a negative number for your distance it is wrong :P

Answer 6

(-4,1), (1,1), and (1, -11) those are your points i'll name them
a b c

therefore use d formula

a to b

b to c
and

c to a :)

and just add all 3 distances.

Answer 7

yeah what he said. You need to find the distance between the points and once you find that you just add them up.

All you do is get your three points and find the distance between them by plugging in the points into the equation : \[\sqrt{(x _{f}-x _{i})+(y _{f}-y _{i})}\]

then once you get those distances add them up
