58.75

35.25

57.25

Answer 1

@perl

Answer 2

@MARC_ can u help ?

Answer 3

@mathmath333 ?

Answer 4

it is given that the two figures are similar

so their sides must be proportional

hence

\(\large \begin{align} \color{black}{\dfrac{12.5}{2x+1}=\dfrac{7.5}{3} \hspace{.33em}\\~\\
}\end{align}\)

see if that makes sense

Answer 5

solve for \(\large x\) now

Answer 6

ok x = 2

Answer 7

@mathmath333

Answer 8

yes \(\Huge \checkmark\)

Answer 9

ok so what do i do next

Answer 10

\(\large \begin{align} \color{black}{\dfrac{y+5}{4.5}=\dfrac{7.5}{3} \hspace{.33em}\\~\\
\dfrac{17.5}{14z}=\dfrac{10}{4} \hspace{.33em}\\~\\
}\end{align}\)

similarly find \(y\) and \(z\)

Answer 11

y = 6.25
z = 0.5

Answer 12

yes correct !

so perimeter of

\(\large \begin{align} \color{black}{POWEQ=PO+OW+WE+EQ+PQ\\~\\ \hspace{.33em}\\~\\
=4.5+3+2x+1+14z+4\\~\\ \hspace{.33em}\\~\\
}\end{align}\)

substitute the value of \(x\) and \(z\) and get the answer

Answer 13

ok so i got 2x + 14z + 12.5

Answer 14

2(6.25) + 14(0.5) + 12.5 = 12.5 + 7 +12.5
= 32

Answer 15

i dont think thats how i do it right?

Answer 16

plz help me x[

Answer 17

after i got 2x + 14z + 12.5 i dont know what to do next

Answer 18

@mathmath333

Answer 19

well i m getting \(23.5\)

Answer 20

something is wrong in here

2(6.25) + 14(0.5) + 12.5 = 12.5 + 7 +12.5
= 32

Answer 21

yea i know

Answer 22

well retry
