The coordinates of the vertices of △abc are a(-2,2), b(5,-3), and c(-4,-1). identify the perimeter of △abc. round each side length to the nearest tenth before adding.

The distance from (-2,2) to (5,-3) is 8.6,  

(5,-3) to (-4,-1) is 9.2

(-4,-1) to (-2,2) is 3.6

add them all together to get the perimeter  

8.6+9.2+3.6= 21.4

so the perimeter is 21.4

step-by-step explanation:

because i said it is

just sum

10 + 10 = 20
