Thanks; let me read your reply.

It might take a few mins,ok?

60 in,yes?

for perimeter of rectangle FGHJ, use the formula :
perimeter = 2(l+w) = 2(20+40) = 2 * 60 = ... in

yes, that's right
sorry, the unit for area must be in squared not in :)

ok, thank u! so, how should I state my answer?

You can call me '123', by the way.

lol. :D

opss.. 20 * 40 = 800 not 80
my stupid --"

nope. so, what should i write for number 1?

800 in^2

oK. But 1 is asking how the area was affected by the dilation.

it can be :
area = 16 times of the area of before do dilated

Oh,ok. Let me write that down .

or '16 times the original area'?

yes

4^2

Ok, thx

i told you that trick before, enchilada

I'm forgetful. SORRY. HAHHAHAHAHA

Oh. okay.

if you're doing volume, you cube it

So the answer would be is 16 times larger than before?

yea, 16 times the original

Oh, I GET IT! I THINK. THANKS!

The perimeter is.

the perimeter would be 4 times greater

Is that a good drawing?

x is the scale factor.
perimeter: x^1, area: x^2, volume: x^3

thanks. i get it, volume is cubed, area is squared. so the perimeter is .. um..

so since the scale factor is 4...
4^1 = 4. perimeter is 4x the original. is this making sense?

Ahhhh! I GET IT NOW! WOW. I'M SO SLOW. I APOLOGIZE TO YOU BOTH.
