What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit ?

25.6 units

Step-by-step explanation:

From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).

First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

where

are the coordinates of the first point

are the coordinates of the second point

- For AB:

- For BC:

- For AC:

Next, now that we have our lengths, we can add them to find the perimeter of our triangle:

We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
