Answer 4

you know pythagoras theorem?

Answer 5

HINT : - SPLIT THE DIAGRAM INTO TWO DIFFERENT SHAPES

Answer 6

ok

Answer 7

what do i do after i split the shape

Answer 8

why, won't it be easier to work out EF, FG, GH, HE seperately using Pyth.theo. and then add them all ?

Answer 9

they're asking for perimeter not area...

Answer 10

yes yes yes i was thinking about area

Answer 11

wrestler, yo know how to find EF?

Answer 12

ill see

Answer 13

umm no im not sure how do I

Answer 14

you know Pythagoras theorem?

Answer 15

yea i do

Answer 16

a2 + b2 = c2 is it this

Answer 17

EF^2 = 2^2 + 2^2, correct?

Answer 18

EF=?

Answer 19

yeah that is that so apply that in the figure to to get that(area) did u get that?

Answer 20

EF= 8?

Answer 21

actually sq.root of 8 ;)

Answer 22

think again sqrt 8

Answer 23

if i find the square root of 8 is that the answer

Answer 24

no buddy, you need to do the same for FG, GH and HE, .. GH is easy, its = 2 units

Answer 25

let's do FG now, can you tell me how long it is?

Answer 26

same thing, use the pythag.theor.

Answer 27

HERE WE ARE DEALING WITH THE MAGNITUDE DON'T CARE ABOUT THE NEGATIVE SIGNS

Answer 28

@Openstudier is the above for this question?

Answer 29

I meant negative values in x axis

Answer 30

ok @prowrestler
EF = sqrt 8
FG = sqrt 5
GH = 2
HE = sqrt 13

add them all 4 together and what do u get?

Answer 31

28

Answer 32

wait no

Answer 33

WHO ATE UP THE SQUARE ROOTS

Answer 34

no let me paraphrase it
\[\sqrt{8} + \sqrt{5} + 2 + \sqrt{13} = ?\]

Answer 35

cookie monster ate them ;)

Answer 36

LOL

Answer 37

doing it right now hold on a bit

Answer 38
