Which corresponds to the perimeter of triangle ABC?

____ [38]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

A (-5 , -1)

B (-2, 3)

C (6, -3)

Perimeter = ?

Formula

$d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }$

distance AB $d = \sqrt{(-2 + 5)^{2} + (3 + 1)^{2} }$

$d = \sqrt{(3)^{2} + (4)^{2} }$

$d = \sqrt{(9 + (16) }$

$d = \sqrt{25}$

d = 5

Distance BC $d = \sqrt{(-3 - 3)^{2} + (6 + 2)^{2} }$

$d = \sqrt{(-6)^{2} + (8)^{2} }$

$d = \sqrt{36 + 64}$

$d = \sqrt{100}$

d = 10

Distance AC $d = \sqrt{(-3 + 1)^{2} + (6 + 5)^{2} }$

$d = \sqrt{(-2)^{2} + (11)^{2} }$

$d = \sqrt{4 + 121}$

$d = \sqrt{125}$

d = 11.2

Perimeter = 5 + 10 + 11.2

= 15 + $\sqrt{125}$
