Find the perimeter of the polygon with the vertices X(-1, 3) Y(3,0) and Z(-1,-2). Round your answer to the nearest hundredth.

Question

Whats the answer i'm having some trouble.

Answer 1

use the distance formula, √[(x2-x1)^2+(y2-y1)^2], for XY, YZ and ZX

you can do the math...

XY=√25=5

YZ=√20=2√5

ZX=√25=5

P=5+5+2√5

P=10+2√5

P=10+4.472

P=14.47
