Question

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

Answer 1

U(-2,4), V(3,4), W(3,-4)

VW = 4- -4 = 8

UV = 3- -2 = 5

UW = sqr(5^2+8^2)

= sqr(25+64) = sqr89

Perimeter = VW+UV+UW = 8+5+sqr89 = 13+sqr89

= about 13 + 9.43

= slightly more than 22.43 rounded off to the nearest hundredth

the polygon is a triangle
