What is the perimeter of triangle ABC?

24 units.

Step-by-step explanation: Count out how many units long AB is. AB goes from -3 to 3, for a length of 6 units.

Count out how long AC is. AC goes from 4 to -4, for a length of 8 units.

To find BC, use the Pythgorean theorem (a^2+b^2=c^2). 8^2 is 64, and 6^2 is 36. Add 64 and 36 to get 100. Then find the square root of 100, which is 10.

Add all the lengths. 6+8+10=24.
