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
