THE PERIMETER OF RECTANGULAR PHOTO IS 24CM ITS LENGHT IS 8 CM WHAT IS BREADTH OF PHOTO​

Answer 1

Question:-

THE PERIMETER OF RECTANGULAR PHOTO IS 24CM ITS LENGHT IS 8 CM. WHAT IS BREADTH OF PHOTO?

Answer:-

• The breadth of rectangle is 4 cm

To find:-

• Breadth of rectangle

Solution:-

• Perimeter of rectangle = 24 cm
• Length of rectangle = 8 cm

As we know,

$\large{ \boxed{ \mathfrak{perimeter = 2(l + b)}}}$

Where,

• l = length of rectangle
• b = breadth of rectangle

According to question,

$\large{ \rm : \implies \: \: \: \: \: \: \: 2(8 + b) = 24}$

$\large{ \rm : \implies \: \: \: \: \: \: \: 8 + b = \frac{24}{2} }$

$\large{ \rm : \implies \: \: \: \: \: \: \: 8 + b = 12}$

$\large{ \rm : \implies \: \: \: \: \: \: \: b = 12 - 8}$

$\large{ \rm : \implies \: \: \: \: \: \: \: b = 4}$

Hence,

The breadth of rectangle is 4 cm.

Let the breadth of rectangular photo be "b"

$\:\:$

$\underline{\bold{\texttt{Perimeter of rectangle :}}}$

$\:\:$

➠ P = 2(L + B)

$\:\:$

Where ,

$\:\:$

• P = Perimeter

• L = Length

• B = Breadth

$\:\:$

$\underline{\bold{\texttt{Perimeter of rectangular photo :}}}$

$\:\:$

• P = 24

• L = 8

• B = b

$\:\:$

➜ P = 2(L + B)

$\:\:$

➜ 24 = 2(8 + b)

$\:\:$

➜ $\sf \dfrac { 24 } { 2 } = 8 + b$

$\:\:$

➜ 12 = 8 + b

$\:\:$

➜ b = 12 - 8

$\:\:$

➨ b = 4

$\:\:$

• Hence the breadth of rectangular photo is 4 cm
