Question

3. Length and breadth of a rectangle are 12 m and 10 m respectively. Find its
perimeter.


​

Answer 1

Correct Question:-

Length and breadth of a rectangle are 12 m and 10 m respectively. Find its perimeter.

Given:-

• Length of rectangle = 12 m
• Breadth of rectangle = 10 m

To Find:-

• Perimeter of rectangle

Solution:-

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: \mathfrak{ \underline{ \green{ Formula \: to \: calculate \: the \: perimeter \: of \: rectangle}}}$

$\boxed{ \boxed{ \red{ \mathfrak{ \star \: \: \: \: \: \: { \large{ \blue{perimeter = 2(length + breadth)}}}}}}}$

According to question,

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: perimeter = 2(12 + 10)}$

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: perimeter = 2 \times 22}$

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: perimeter = \boxed{\mathfrak{ \red{ \underline{ 44 \: m}}}}}$

Hence,

• The perimeter of rectangle is 44 m

Answer 2

Answer:

In a rectangle,

length =12 m

breadth=10 m

perimeter=2(l+b)

=2*(10+12)

=2*22

=44 m
