Question

How do I do this I'm confused

Answer 1

Explanation:

length can be find out by using the formula

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

now put values

`√((2-2)^2+(0-6)^2) \\`

`√(0+(-6)^2) \\`

`√(36 ) \\`

`6`

similarly

`|CD| = √((12-0)^2+(-10+6)^2) \\`

`√(144+16) \\`

`√(160) \\`

`4 √(10) \\`

and finally

`|EF| = √((-3-6)^2+(2-2)^2) \\`

`√(81) \\`

`9 \\`

i hope u will understand
