Group Title
Two rectangles are similar. Rectangle ABCD has a length of 5 in and a width of 10 in. Rectangle ABCD is dilated by a scale factor of 4 to form rectangle FGHJ. Answer these questions using the information provided:
1. How is the area affected by the dilation?
2. How is the perimeter affected by the dilation?

to get the length and the width of rectangle of FGHJ, just multiply by 4 from the length and the width of rectangle ABCD. so, l = 4 * 5 = 20 w = 4 * 10 = 40 now, to get area use the formula : area = length * width = 20 * 40 = .... in

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 :)

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

oppss.. my eyes still want to bed, @123 :) area = 20 * 40 = 80 in^2 not 60 (sorry) perimeter = 2(20+40) = 2(60) = 120 in

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'?

for area, you square the amount of times it changed. like, if the scale factor is 3, 3^2 = 9. so the area would be 9 times greater

if you're doing volume, you cube it
 one year ago

help123please. Group TitleBest ResponseYou've already chosen the best response.1
So the answer would be is 16 times larger than before?

yea, 16 times the original

The perimeter is.

Is that a good drawing?

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

help123please. Group TitleBest ResponseYou've already chosen the best response.1
thanks. i get it, volume is cubed, area is squared. so the perimeter is .. um..
 one year ago

AriPotta Group TitleBest ResponseYou've already chosen the best response.0
so since the scale factor is 4... 4^1 = 4. perimeter is 4x the original. is this making sense?
