Answer 1

Pls mark as brainliest answer

Answer 2

AnswEr:-

Ratio of width to perimeter = 1 : 8

Step-by-step-explanation:-

☯Given :-

• Width of picture = 60 cm
• Length of picture = 1.8 m

☯To find :-

• Ratio of width to perimeter = ?

☯Solution :-

Here,

➩ Width = 60 cm

➩Width = 60/100 m [1 m = 100 cm]

➩ Width = 0.6 m

Now,length = 1.8 m

We know,

$\star\:\large{\boxed{\sf\green{Perimeter_{rectangle} = 2(l + b) }}}$

• Putting values:-

⇒ Perimeter = 2(1.8 + 0.6)

⇒ Perimeter = (2 × 2.4) m

⇒ Perimeter = 4.8 m

$\rule{200}1$

☯Ratio :-

➩ Width : Perimeter = 0.6 : 4.8

➩ Width/Perimeter = 0.6/4.8

➩ Width/Perimeter = 1/8

➩ Width : Perimeter = 1 : 8

$\therefore{\underline{\textsf{Ratio \: of \: width \: to \: perimeter = {\textbf{1 : 8 }}}}}$
