Answer 1

☆ Correct Question ☆

Find the perimeter of rectangle whose length is 12 cm and breadth is 9cm.

☆ Solution ☆

Given :-

• The length of rectangle = 12 cm
• The breadth of rectangle = 9 cm

To Find :-

• The perimeter of rectangle.

Step-by-Step-Explaination :-

As we know that :-

Perimeter of rectangle = 2 ( l + b )

Putting the respective value,

Perimeter of rectangle = 2 ( 12 + 9 )

Perimeter of rectangle = 2 × 21

Perimeter of rectangle = 42

Hence,

Perimeter of rectangle = 42

Answer 2

Question:-

Find the perimeter of rectangle whose length is 12 cm and breadth is 9cm

Answer:-

• The perimeter of rectangle is 42 cm

To find:-

• Perimeter of the rectangle

Solution:-

• Length of rectangle = 12 cm
• Breadth of rectangle = 9 cm

As we know,

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

Where,

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

According to question,

$\Large{ \sf : \implies \: \: \: \: \: \: \: perimeter = 2(12 + 9)}$

$\Large{ \sf : \implies \: \: \: \: \: \: \: perimeter = 2 \times 21}$

$\Large{ \sf : \implies \: \: \: \: \: \: \: perimeter = 42}$

Hence,

The perimeter of rectangle is 42 cm
