See the attached image and use it to answer the following questions:
1. What is the scale factor used to dilate the figure?
2. What is the perimeter of the original figure?
3. What is the perimeter of the dilated figure?
4. How is the perimeter affected by the dilation?
5. What is the area of the original figure?
6. What is the area of the dilated figure?
7. How is the area affected by the dilation?

8/3 = 6/3?
OpenStudy (aripotta):
brb
OpenStudy (aripotta):
and it's 8/4, not 8/3

THE SCALE FACTOR IS 2!!!!
OpenStudy (anonymous):
ISNT IT?! WOW I FOUND IT! THATS SURPRISING!
OpenStudy (anonymous):
Ok, let me write it down....
OpenStudy (anonymous):
The perimeter is 28.
OpenStudy (anonymous):
For the original.

OpenStudy (aripotta):
omg. i think we've been doing it wrong the whole time. the scale factor is 1/2
OpenStudy (anonymous):
what?
OpenStudy (anonymous):
why? how?when?where?
OpenStudy (aripotta):
who?
OpenStudy (anonymous):
lol. it was a joke.

How did we make a mistake?
OpenStudy (aripotta):
and yea, 29 is right
OpenStudy (aripotta):
28*
OpenStudy (anonymous):
Yes. Is the scale factor wrong?
OpenStudy (aripotta):
the scale factor is 1/2
4/8

OpenStudy (aripotta):
it has to be new over original
OpenStudy (anonymous):
1/2.
OpenStudy (aripotta):
i'm sorry :c
OpenStudy (anonymous):
Oh.

Uhm, 4/8.
OpenStudy (anonymous):
Hmmm.
OpenStudy (anonymous):
Okay.
OpenStudy (anonymous):
So, I'll write '1/2'.
OpenStudy (aripotta):
the perimeter should be 1/2 the original

so that answers 4
OpenStudy (anonymous):
Oh,okay.
OpenStudy (aripotta):
and 3 would be 28/2 which is 14
OpenStudy (anonymous):
Thanks.
OpenStudy (anonymous):
So, 3 is 28/2.14.ok.

Oh. [you said perimeter is 1^x]
OpenStudy (aripotta):
x^1

one second.
OpenStudy (aripotta):
area is x^2
OpenStudy (anonymous):
It is now 1/2 the size of the original?

right. thanks ! i only have the 3's times tables memorized. lol
OpenStudy (aripotta):
remember x^2 for area. so 1/2^2
OpenStudy (anonymous):
Okay. *REMEMBERS*

Yes, I memorized the 1^x, 2^x,, and 3^x.

why do i do it backwards???? dang. forgive me.

x being the scale factor, yes?

1/2^2 = ?
OpenStudy (anonymous):
so the dilated figure;s area.
OpenStudy (anonymous):
uhm.... .25
OpenStudy (aripotta):
yea, or 1/4. so the new area should be 1/4 the original. 48/4 = ?
