Find the perimeter of the polygon with the vertices

Question

Find the perimeter of the polygon with the vertices U(−2, 4), V(3, 4), and W(3,−4). Round your answer to the nearest hundredth.

Answer 1

vertices U(−2, 4), V(3, 4), and W(3,−4)

 

length of UV=√((-2-3)²  + (4-4)²)  = √25 =5

 

length of VW =√((3-3)² +(4+4)² ) =√64 =8

 

length of UW =√((-2-3)² +(4+4)² ) =√(25 +64) =√89

 

perimeter = UV+VW+UW=5+8+√89=13+√89

=13 + 9.434 =22.434
