Question

12) If the length and breadth of a rectangle are 36 cm and 24 cm respectively.
Find perimeter ​

Answer 1

Answer:

120 cm

Step-by-step explanation:

l = 36cm

b = 24cm

perimeter = 2 ( l + b )

= 2 ( 36 + 24 ) cm

= 2 ( 60 ) cm

= 120cm

Answer 2

Answer:

We have given rectangular piece whose Length and breadth are 36 cm and 24 cm respectively.

We have to find out the perimeter of the plot.

Formula need to know :

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

Where,

" l " = Length

" B " = Breadth

Now, lets find out the Perimeter :

$\underline{\sf Solution :}$

$\longrightarrow\:\:\sf Perimeter \: of \: rectangle = 2(Length + Breadth)$

$\longrightarrow\:\:\sf Perimeter \: of \: rectangle = 2(36 + 24)$

$\longrightarrow\:\:\sf Perimeter \: of \: rectangle = 2(60)$

$\longrightarrow\:\: \underline{ \boxed{\sf Perimeter \: of \: rectangle = 120 \: cm}}$

In the similar way, we can also find the area of the rectangle :-

Formula for Area :

${\boxed{\sf{Area \: of \: rectangle = Length \times breadth}}}$

$:\implies \sf Length \: (l) = 36 \: cm$

$:\implies \sf Breadth \: (b) = 24 \: cm$

Putting up the respective values, we get -

$\dashrightarrow\:\:\sf Area = L \times B$

$\dashrightarrow\:\:\sf Area = 36 \times 24$

$\dashrightarrow\:\:\sf Area = 864$

$\dashrightarrow\:\: \underline{ \boxed{\sf Area \: of \: rectangle = 864 \: {cm}^{2} }}$
