The perimeter of rectangle is 120 centimetre its length is 35 cm find its breadth..

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

✰✰ Answer ✰✰

$\small{\boxed{\bold{\bold{\red{\sf{Length⟹35cm}}}}}}$

$\small{\boxed{\bold{\bold{\blue{\sf{Breadth⟹?}}}}}}$

$\small{\boxed{\bold{\bold{\green{\sf{Perimeter\:of\:Rectangle⟹120cm}}}}}}$

$⟹2 ( l + b ) = 120cm$

$⟹2 ( 35 + b ) = 120 cm$

$⟹ 35 + b = \cancel\dfrac{120}{2}$

$⟹35 + b = 60$

$⟹b = 60 - 35$

$⟹ b = 25 cm$

$⟹\large{\boxed{\bold{\bold{\purple{\sf{Breadth = 25cm}}}}}}$

Answer 2

$\huge \underline \mathbb {SOLUTION:-}$

Answer:

• The breadth of the rectangle is 25.

Given:

• The perimeter of rectangle is 120 centimetre.
• The length of the rectangle is 35 centimetre.

Need To Find:

• The breadth of the rectangle = ?

Explanation:

Formula used here:

• Perimeter of rectangle = 2(l + b)

Here:

• L is used for Length.
• B is used for Breath.

Putting the values according to the given formula:

➠ 120 = 2(35 + b)

➠ 120 = 70 + 2b

Or 70 + 2b = 120

➠ 2b = 120 - 70

➠ 2b = 50

➠ b = 50/2

➠ Breadth = 25

• Hence, The breadth of the rectangle = 25.

Additional Information:

• The length of the boundary of a closed figure is called the Perimeter.
• Perimeter of a square = 4 × side.
• Perimeter of a rectangle = 2 × (length + breadth).
