Question

find the perimeter of rectangle where length is 7cm and breadth is 8cm​

Answer 1

Answer:

2 × (l + b)

2 ×( 7 + 8)

30 cm is your answer

btw how can length be 7cm and breadth 8cm. i think you just reversed both of them.

Answer 2

Given :

• Length of Rectangle = 07cm

• Breadth of Rectangle = 8cm cm

$\begin{gathered} \\ \\ \end{gathered}$

To Find :

• Perimeter of Rectangle = ?

$\begin{gathered} \\ \\ \end{gathered}$

Solution :

${\underline{\sf\maltese \mathfrak{ \pmb{Formula Used :}}}}$

• ${\underline{\boxed{\sf{ Perimeter = 2 \bigg(Length + Breadth \bigg) }}}}$

Where :

• ➻ Length= 7 cm

• ➻ Breadth = 08 cm

$\begin{gathered} \\ \qquad{\rule{150pt}{1pt}} \end{gathered}$

~Calculating The Area :

${\dashrightarrow{\qquad{\sf{ Perimeter = 2 \bigg(Length + Breadth \bigg) }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ = 2 \bigg(8 + 7 \bigg) }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ 2 \times8 + 7 }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ 2 \times 15}}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ 2 \times 15 = 30 }}}} \\ \\ \\ \ \\ \\ \\ \ {\qquad \; \; {\therefore \; {\underline{\boxed{\pink{\pmb{\frak{ Area = 30\; cm }}}}}}}}$

$\begin{gathered} \\ \qquad{\rule{150pt}{1pt}} \end{gathered}$

~Therefore

❛❛ Perimeter of the given Rectangle is 30cm . ❜❜

$\begin{gathered} \\ {\underline{\rule{300pt}{9pt}}} \end{gathered}$
