Question

Find the perimeter of a quadrilateral with vertices at C (-1, 2), D (-2, -1), E (2, -2), and F (1, 1). Round your answer to the nearest hundredth when necessary.

A. 10.92 units
B. 12.68 units
C. 13.43 units
D. 18.27 units

Answer 1

B 12.68

Explanation:

you will need to find the distance between each segment-

so the length of DC, CF, FE, ED

DC:

D(-2,-1) C(-1,2)

CF:

C(-1,2) F(1,1)

FE

F(1,1) E(2,-2)

ED

E(2,-2) D(-2,-1)

3.16+2.24+3.16+4.12= 12.68
