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.

Answer 1

10.92 units
12.68 units
13.43 units
18.27 units

Answer 2

please help, been up all night doing hw

Answer 3

The perimeter is just the sum of the lengths of the sides.
Meaning that you have to find the distance of:
-CD
-DE
-EF
-FC

Use the distance formula:
\[dist(p_1 , p_2 )=\sqrt{(x_2-x_1)^2 + (y_2-y_2)^2}\]

Answer 4

CD=10
DE=17
EF=10
FC=5

Answer 6

good, now add them together.
meaning that the perimeter of this quadrilateral will be the sum of the lengths of its sides

Answer 7

I got 42

Answer 8

What else do I do?

Answer 9

Nvm I got it

Answer 10

Thank for your help and for future people you square root those numbers and add them together giving you choice B
