Atriangle has verices at (4,-2), (-3,0) and (1,3). what is the approximate perimeter of the triangle? 1. 17 units 2.18 units 3.19 units 4.20 units

Hello

You have three points and need to find the distances between each pair of them.  You can do this with the Pythagoras theorem applied to each: For the first pair (1, 3), (2, -3)(2 - 1) is the change in distance between the x-coordinates and(3 - -3) is the change in distance between the y (2 - 1)2 + (3 + 3)2 = c21 + 36 = c2c = √37 Repeat for (2, -3), (-1, -1) and(-1, -1), (1, 3) Add your c's together and you will have your perimeter

Have a nice day
