Question

the length of rectangle is 40 m and breadth is 50m
Find the perimeter of rectangle?​

Answer 1

Answer :-

• The perimeter of the rectangle is 180 m.

Given :-

• The length of the rectangle = 40 m.
• The breadth of the rectangle = 50 m.

To find :-

• The perimeter of the rectangle.

Step-by-step explanation :-

• Here, the length and breadth of a rectangle have been given to us. We have to find it's perimeter.

We know that :-

$\underline{\boxed{\sf Perimeter \: of \: a \:rectangle = 2 \: ( L + B)}}$

Where,

• L = Length.
• Breadth.

Here,

• Length = 40 m.
• Breadth = 50 m.

---------------------

Hence,

$\rm Perimeter = 2\: (40 + 50)$

Adding the numbers inside the brackets,

$\rm Perimeter = 2\: (90)$

Removing the brackets,

$\rm Perimeter = 2 \times 90$

Multiplying 2 with 90,

$\overline{\boxed{\rm Perimeter = 180 \:m}}$

---------------------

• Hence, the perimeter of the rectangle is 180 m.

Answer 2

$\huge \star \: { \boxed{ \underline{ \mathfrak{ \purple{Answer}}}}}$

$\sf \: perimeter \: of \: rectangle = 2(length + breadth)$

$\implies \: 2(40 + 50)$

$\implies2 \times 90m$

$\implies \: 180m$

$\\ \: \: \: \: \: \: \boxed{ \sf{ \underline{ \red{ \therefore \: Perimeter \: of \: rectangle \: is \: 180m}}}}$
