1 Graph the polygon ABCDEF which has coordinates, on the coordinate grid vertices at the following below. A(-4, y, B(6, 7), c(6, -2, D(-8, -2, E(-8, 3, F( 4, 3) What is the perimeter of polygon ABCDEF? Answer units

Solution

Sides of polygon are AB , BC, CD, DE, EF, FA

( -4 , 7) ( 6, 7) ; AB = sqrt[ ( 0^2 + 10^2) = 10

( 6 , 7) (6 , -2) ; BC = sqrt[ (9^2 ] = 9

(6 , -2) (-8 , -2) CD = sqrt[14^2] = 14

( -8, -2) (-8, 3) , DE = 5

( -8, 3) ( -4,3 ) EF = 4

( -4, 3) (-4, 7) , FA = 4

So, Perimeter = sum of all sides = 46 units
