Question

What is the perimeter of triangle ABC? 20 units 22 units 24 units 26 units

Answer 1

8[2] + 6[2] = c[2]
64 + 36 = c[2]
100 = c[2]
c = 10

8 + 6 + 10 = 24 units

Answer 2

Answer:

Step-by-step explanation:

Alright, lets get started.

The points of given triangle is :

point A  (-3, 4)

point B  (3, 4)

point C  (-3, -4)

Using distance formula :

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

$AB=6$

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

$AC=8$

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

$BC=10$

So the perimeter is = sum of all three sides

So, the perimeter = $6+8+10 = 24$

So the answer is 24 units.   :     Answer
