Question

How do I do this I'm confused

Answer 1

Step-by-step explanation:

length can be find out by using the formula

$|AB| = sqrt{(x1-x2)^2+(y1-y2)}$

now put values

$\sqrt{(2-2)^2+(0-6)^2}$

$\sqrt{0+(-6)^2}$

$\sqrt{36 }$

$6$

similarly

$|CD| = \sqrt{(12-0)^2+(-10+6)^2}$

$\sqrt{144+16}$

$\sqrt{160}$

$4 \sqrt{10}$

and finally

$|EF| = \sqrt{(-3-6)^2+(2-2)^2}$

$\sqrt{81}$

$9$

i hope u will understand
