Answer 2

@ayee_ciera what is the edge of your square?

Answer 3

idk it doesnt say

Answer 4

the diagonal forms the hypotenuse of a right triangle. so you can use pythagorean theorem

Answer 5

ok! keep in mind that if l is the edge of your square, then, we have:
\[l ^{2}=200\]

Answer 6

ok

Answer 7

ok! so in order to find l, you have to calculate this:
\[l=\sqrt{200}\]

Answer 8

i got 14.14 which equal 10 square rooted 2

Answer 9

so its c

Answer 10

that's right! \[10\sqrt{2}\]

Answer 11

thx (:

Answer 12

wait please!

Answer 13

k

Answer 14

you jnow the edge, nevertheless you have tocalculate the diagonal

Answer 15

sorry you know the edge...

Answer 16

in order to findi the diagonal, please keep im mind this:

Answer 17

alright

Answer 18

please apply the pitagora theorem

Answer 19

\[l ^{2}+l ^{2}=d ^{2}\]

Answer 20

so:
\[200+200=d ^{2}\]

Answer 21

@ayee_ciera
