The coordinates of the vertices of a polygon are (−3, 2) , (2, 3) , (4, 1) , (1, −1) , and (−3, −1). Round each side length to the nearest tenth of a unit.

What is the perimeter of the polygon?

Respuesta :

Length of AB is [tex] \sqrt{(y2-y1)^2+(x2-x1)^2} [/tex]

AB=[tex] \sqrt{26} [/tex]=5.09
BC=[tex] \sqrt{8} [/tex]=2.82
CD=[tex] \sqrt{13} [/tex]=3.6
DE=4
EA=3

perimeter=add all sides= 18.51
