Answer 1

50

Answer 2

how did you get the answer?

Answer 3

the left rectangular has the sides are 39 ,12. the perimeter is (39 +12)*2 = 102

Answer 4

the right rectangular has the sides is 1, x . the perimeter is (1+x)*2 = 102. since you said that they are similar.
solve for x . I get x=50

Answer 5

is it clear?

Answer 6

can u show me how u did it using proportions?

Answer 7

you mean the scale?

Answer 8

yes, please.

Answer 9

you don't have the proportion in this case. since the rectangular are similar all. they are not triangles. so, the similar means the perimeter or the area are the same. when you have a rectangular, one side shrink and the new rectangular not change ( similar to the original one) , the other side of the rectangular must be last long to get it ( the area or perimeter)not change

Answer 10

i asked for them as I must show work using proportions. But mmk, thanks

Answer 11

don't be confused by the picture. all picture in math is not in scale.
I don't know, may be it not help. so anyway, i try all

Answer 12

ok.

Answer 13

Answer 37

@agent0smith

Answer 38

Since they're similar, just like similar triangles, the ratios of side lengths should be the same:

12:1 and 39:x, or 1:12 and x:39
\[\frac{ 1 }{ 12} = \frac{ x }{ 39 }\]

Answer 39

tnx u

Answer 40

let me solve

Answer 41

3.25

Answer 42

x = 3.25 is correct :)

Answer 45

tnx u!

Answer 46

will fan

Answer 47

\[\frac{ 39 }{ 12 } = x\]
\[x = 3.25\]

Answer 48

thanks!

Answer 49

No prob :)
