$\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}$

$\implies$ Here it is given in the question that the length and breadth of a rectangle is 8cm and 4 cm respectively. Now the question has asked us to find out the perimeter of the given rectangle.

⛤ HOW TO DO:-

$\to$ To find the perimeter of rectangle we have to use a certain formula. We have to solve by putting the values and the final digits will be the answer. First of all we have to add the length and breadth. Then after we have to multiply it with 2. This is how we will get the perimeter of the given rectangle.

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

ANSWER:-

✦ The perimeter of the given rectangle is 24 cm.

GIVEN:-

➟ Length of the rectangle = 8 cm

➟ Breadth of the rectangle = 4 cm

TO FIND:-

• Here we have to find the perimeter of the given rectangle.

SOLUTION:-

• To find the perimeter we have to apply a certain formula.
• So let's find the perimeter of the given rectangle.

We know that:-

$\pink{\bigstar} \: \underline{\boxed{\rm {\green{Perimeter\:of\:rectangle = 2(L + B)}}}}$

Where,

• Length = 8 cm
• Breadth = 4 cm

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

So let's solve it!

• Finding the perimeter:-

$\dashrightarrow \tt{Perimeter = 2(8 \: cm + 4 \: cm)}$

$\dashrightarrow \tt{Perimeter = 2(12 cm)}$

$\dashrightarrow \tt{Perimeter = 2 \times 12 \: cm}$

$\dashrightarrow \tt{Perimeter = 2 \times 12 \: cm = 24 \: cm}$

$\pink{\odot} \: \underline{\boxed{\rm {\green{Perimeter = 24 \: cm}}}}$

Thus we got the answer.
