Question

HELP PLEASE!

Answer 1

@Directrix

Answer 2

I agree with your area calculations. I need a second to be sure all the parts were used. Whoever drew this diagram is really good with graphics.

Answer 3

^-^ it was @Lessis ♥ she tried to help me but i just understood till here.-.

Answer 4

Okay, the sum is ? @Thatyoungbuttercup

I'm going to find the thread and give her a medal because it is a great drawing, and I cannot do them so I admire those who can.

Back to business, what is the sum of all those areas? That is what you want to find at this point.

Answer 5

kk wait let me add them! i got 29.5 when i add them all up

Answer 6

I got 29.5 square units and checked.

Answer 7

wait but theres 2 triangles that are 3 no?

Answer 8

You are talking about those two blue ones that merged together, right?

Answer 9

The answers

Answer 10

@Thatyoungbuttercup

Answer 11

yeah those 2

Answer 12

Those two merged together so all you have to do is to use the area of the larger one. Your friend was showing you how to put two together and save a little time. It is a good technique. So, just use the area of the larger one.

Answer 13

wait so is the area 29.5 then or 32.5?

Answer 14

The area is 29.5

Answer 15

got it! so you take the area of the bigger one right?

Answer 16

kk can you help me with the other one?

Answer 17

Yes. Will you post it in a new thread, please? Thanks.

Answer 18

kk hold up!

Answer 20

@Directrix

Answer 21

I am posting just second problem.

Did you work on that last night?

Answer 22

YEAH A BIT BUT ITS NOT RIGHT HTOUGH

Answer 23

Did Lessis make a diagram? I'm just trying to figure out where we are. Maybe we should start at the beginning.

Answer 24

NO SHE DIDNT :( i thought of adding all the sides for the perimeter but idk

Answer 25

Let me see if we have all the side lengths.

Answer 26

We have most but not all of them.

Answer 27

but can you assume some sides though?

Answer 28

You have a huge rectangle minus 3 rectangles that you removed.

Answer 29

Hey @Lessis That is a great idea. Are you up to doing the diagram again?

Answer 30

so do i add all the sides?

Answer 31

I need @Lessis to check my 8 by 8 square.

Answer 32

Yes.

Answer 33

Is the huge rectangle an 8 by 8 square?

Answer 34

0--o

Answer 35

@Thatyoungbuttercup >>so do i add all the sides?

Yes but we don't know all of them yet.

Answer 36

The square would have area 64 but we have to subtract the "empty" rectangles that are not part of the original figure.

Answer 37

i though the area was 64 though cause 8 times 8=64

Answer 38

We are doing area while @Lessis is drawing.

So, take the 64 and subtract the area of the three red regions to get the area of the problem. Okay?

Answer 39

@Thatyoungbuttercup Did you get 64 - 6 - 4 - 6 = ? for the area?

Answer 40

i got 48 for the area

Answer 41

Yes, that is what I got.

Answer 42

so 48 is the area right?

Answer 43

Yes, that is what I calculated.

Answer 44

Then, there is perimeter to do.

Answer 45

:( i know but for that one dont you add all the sides?

Answer 46

Yes. The question is this --> do we know all the sides yet?

Answer 47

Just a second. I need to draw.

Answer 48

sooooooooo what? 0_o i mean i get it but its just 0_o

Answer 49

The total area is the area of the purple square, minus the area of the red, green and blue figures.

Answer 50

so @Directrix was right then

Answer 51

To calculate the perimeter, you just add up the length of the black lines. The black lines that you do not know the length of, are obtained from the red green and blue figures.

Answer 52

i got 42 as my perimeter

Answer 53

@Directrix ? is it right?

Answer 54

Correct! Now you know the answer to life, the universe and everything.

Answer 55

42 is what I got.

Answer 56

OMFG I KNOW!♥ THANKS SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 57

What a difference a good diagram makes! Thanks, @Lessie

And, thanks to you @Thatyoungbuttercup for being an active participant in all of this. I really enjoyed working with the two of you.

Answer 58

@Lessis, that is!

Answer 59

Seriously though, if you didn't get the reference, google "What is the answer to life, the universe and everything?"

Answer 60

THANKS SO MUCH YOU GUYS!

Answer 61

I'll do that @Lessis

Thanks, again, everyone.

Answer 62

I fan you @Directrix

Answer 63

Thank you @Directrix

Answer 64

You are welcome. And, thank you.
