Help me please

OpenStudy (anonymous):

OpenStudy (nubeer):

perimeter = 2 (L+W) Area = Length * height

OpenStudy (anonymous):

So I multiply the 3 numbers right?

OpenStudy (anonymous):

I got 324 but still telling me its the wrong answer

OpenStudy (nubeer):

hmm 3 numbers? no. for perimeter = 2 (length + width)

OpenStudy (anonymous):

That would be 18 into 6

OpenStudy (nubeer):

no.

OpenStudy (anonymous):

18 x 3=54

OpenStudy (nubeer):

18 plus 6 not into

OpenStudy (anonymous):

18 plus 6 is 24

OpenStudy (nubeer):

yes multiply it with 2 .. thats your perimeter

OpenStudy (anonymous):

so 24 is my answer

OpenStudy (nubeer):

excuse me? i wrote the formula above u just have to plug in the values..

OpenStudy (anonymous):

ughhh can you just please give me the answer

OpenStudy (anonymous):

I am so confused

OpenStudy (nubeer):

well i would but this is not a homework site

OpenStudy (anonymous):

Bhaijaan please

OpenStudy (nubeer):

lol still that's a no.. i wrote the formula done half of your problem.. u can do it from there..

OpenStudy (anonymous):

So I multiply what number 18 and 3 and then multiply it by 2

OpenStudy (anonymous):

Help please!

OpenStudy (nubeer):

length is 18 and width is 6 , height is 3 just plug the values in formula u will get the answers

OpenStudy (anonymous):

I am but I end up getting 324. I told you this before man

OpenStudy (nubeer):

i guess then show me your working here..

OpenStudy (anonymous):

18 x 6 x 3= 324

OpenStudy (nubeer):

and why do u multiply aall 3 of them.. go look at formula again i wrote and plug the value in formula

OpenStudy (anonymous):

Okay just multiply the length and the width?

OpenStudy (anonymous):

Then what is my length and the width?

OpenStudy (anonymous):

AREA = HEIGHT * WIDTH PERIMETER = SIDE1 + SIDE2 + SIDE3 + SIDE4

OpenStudy (anonymous):

So multiply length and the width?

OpenStudy (anonymous):

Yes. Multiply the length and the width.

OpenStudy (anonymous):

That would be 18 x 3?

OpenStudy (anonymous):

Yes. Multiply 18 * 3

OpenStudy (anonymous):

54 I get

OpenStudy (anonymous):

Yes. The area is 54

OpenStudy (anonymous):

So the perimeter is 54

OpenStudy (anonymous):

NO!!!!

OpenStudy (anonymous):

Oo now what?

OpenStudy (anonymous):

54 multiply 2

OpenStudy (anonymous):

THE *AREA* IS 54!

OpenStudy (anonymous):

Where do I go from 54 now to find my perimeter

OpenStudy (anonymous):

You don't. The perimeter is completely different. The AREA of something is the space it covers. You need to know AREA to paint a wall or lay a rug. The PERIMETER is the line that surrounds the area. Like a sidewalk going around the edge of a park.

OpenStudy (anonymous):

Yes but I need to find the perimeter, and I dont know how to do it. Can you explain step by step how can I get the perimeter

OpenStudy (anonymous):

I told you that previously, and I'll repeat it here. For your shape: PERIMETER = SIDE1 + SIDE2 + SIDE3 + SIDE4

OpenStudy (anonymous):

So 51?

OpenStudy (anonymous):

Is that right

OpenStudy (anonymous):

You have 4 sides. The 2 short sides are the same length. The 2 long sides are the same length. Therefore, their sum can't be an odd number

OpenStudy (anonymous):

Omg, I still getting 51

OpenStudy (anonymous):

How can you POSSIBLY be getting 51? What numbers are you adding?

OpenStudy (anonymous):

18 18 6 6 and 3

OpenStudy (anonymous):

3 isn't on the edge. 3 is the height. Only add the EDGES together.

OpenStudy (anonymous):

Then 48

OpenStudy (anonymous):

Am I right now?

OpenStudy (anonymous):

Exactly! 18 + 18 + 6 + 6 = 48 = PERIMETER 3 * 18 = 54 = AREA

OpenStudy (anonymous):

Thank You
