Question

The coordinates of the vertices of two rectangles, Rectangle ABCD and Rectangle PQRS are given below.

Rectangle ABCD – A(0, 4), B(9, 4), C(9, -2), D(0, -2)
Rectangle PQRS – P(-4, 6), Q(2, 6), R(2, 2), S(-4, 2)

Leah scaled both the rectangles about their centers to create two congruent rectangles A′B′C′D′ and P′Q′R′S′.

Answer 1

By which factor did she most likely scale Rectangle ABCD and Rectangle PQRS?

Rectangle ABCD by 3 and Rectangle PQRS by 2 to create congruent rectangle of dimensions 3 x 2 units

Rectangle ABCD by and Rectangle PQRS by to create congruent rectangles of dimensions 3 x 2 units

Rectangle ABCD by and Rectangle PQRS by to create congruent rectangles of dimensions 4 x 3 units

Rectangle ABCD by and Rectangle PQRS by 2 to create congruent rectangles of dimensions 2 x 3 units

@terenzreignz

Answer 16

hmm... get the area of the rectangles, I suppose? :)

Answer 17

Or actually, no, just the dimensions--
distance formula?

Answer 18

Could you do that?

Answer 19

like the side of each of the figure?

Answer 20

Yeah. Besides, for each rectangle, you only need to measure two sides, because the other two sides would be equal in length, aye? :)

Answer 21

abcd would be 9x6 i think...

Answer 22

Seems like it

Answer 23

and other is 6x4?

Answer 24

Okay. Good :)

Answer 25

Let's try the first choice. Scale abcd by 3
and then scale pqrs by 2, what happens?

Answer 26

27x18
12x8

Answer 27

Those aren't congruent, are they? :P

Try the other choices ;)

Answer 28

ı found the answer ı will write on paper and ı will take a photo

Answer 29

Wait a minute, I think scale actually means divide, and not multiply, could you try the first choice again?

Answer 30

3x2
3x2

Answer 31

:OOOOOOO

Answer 32

okay? :)

Answer 33

Wanna help me with another broo?

Answer 34

Easier im just confused a little on it

Answer 35

post it and see what happens

Answer 36

I got it broo.. thanks ALOT though...
you did something like 25+ people couldnt..

Answer 37

Nah, they just couldn't find the time ;)

Answer 38

No problem and good work, by the way ^.^

Answer 39

here is the answer

Answer 40

@ex0rcist_6_6_6 I thought scaling was multiplying at first, but then I saw in the choices that all scaling results in smaller rectangles.

Remember that the two rectangles were originally 9x6 and 6x4 respectively, as @Gringo solved :)

Answer 41

ahh sorry about that ı am not focus on this by analogy that ı used is true

Answer 42

I got it wrong -.-

Answer 43

Really? It was multiplying after all?

Answer 44

Yeah :/ I was supposed to multiply by 1/3 and 1/2

Answer 45

multiply by 1/3 and 1/2 ?
-.-
That's the same as dividing by 3 and by 2

Answer 46

Thanks anyways bro.. I wouldve just guessed it and got it wrong

Answer 47

ı look ı used right right lenght 9*6 and 6*4. my answer is correct totally

Answer 48

But which was the correct answer, then?

Answer 49

b

Answer 50

if we kept going we wouldve had it

Answer 51

three of them a full answer my camera cannot take all of them ı take photo partially ıf you look carefully you will understand

Answer 52

Your choice b doesn't have numbers, though ...

Answer 53

yeah I seen exorcist after I seen yours I already posted to see if I got it right

Answer 54

oh wow!!! lol

Answer 55

my answer is d which you scale ABCD by 2 and PQRS by3

Answer 56

cause I copied and pasted it and it didnt bring the fractions -.-

Answer 57

ahh... okay, there's the problem...

Answer 58

d is 1/2 and 2....

Answer 59

okay, I'd have had a complete change of heart if I saw those fractions. I'm really sorry, bro T.T

Answer 60

ıs there any answer that that we scale ABCD by 2 and PQRS by3

Answer 61

no lol

Answer 62

then this question use scaling from the center by differently

Answer 63

Answer 64

when you click show distance it show how scale it.and it is same as ı do in your question

Answer 65

hey at least you got the help :D sorrry aqain icouldnt help you with anythinq.....
