Find the perimeter of a polygon with 5 sides

Question

𝐶 (−1, 1), 𝐷(3, 4), 𝐸(6, 0), 𝐹 (2, −3), 𝐺(−4, −4)

Answer 1

CD^2 = 9+16 = 25

CD = 5

DE = sqr25 = 5

EF = sqr25 = 5

FG =sqr37

CG = sqr34

perimeter = 15 + sqr37 + sqr34

just use the distance formula distance squared = sum of the squares of change in x plus change in y, use it 5 times to get 5+5+5+sqr37 +sqr34
