The first thing you do is cross multiply which is 3/4x=48 (3/4 = 0.75). Therfore you divide each side by .75. The left side cancels out. For the right side you divide 48 by .75 and gives you 64. x=64

Find the perimeter of the

seraphim [82]

Answer:

$\huge \boxed{ \boxed{ \sf parimeter = 150cm}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

similarity
PEMDAS
equation

<h3>tips and formulas:</h3>

when two shapes are similar the rotio of two sides or area or parimeter is equal

<h3>let's solve:</h3>

$step - 1 : define$

let the parimeter of second shape be x

$\sf \frac{48}{60} = \frac{120}{x}$

$step - 2 : solve$

$\sf cross \: multiplication : \\ \sf 48x =72 00$
$\sf divide \: both \: sides \: by \: 48 : \\ \sf \frac{48x}{48} = \frac{7200}{48} \\ \therefore x = 150$
