Question

Find the perimetre of a rectangle, where its lengh 'l' and breadth 'b'

pls I need it now :(​

Answer 1

Answer:

• 2(l+b) is the required perimeter of Rectangle.

Step-by-step explanation:

According to the Question

It is given that,

• Length of rectangle = l

• Breadth of Rectangle = b

we have to calculate the Perimeter of the rectangle .

As we know that perimeter of any polygon is calculated by the sum of length of its side . Rectangle has 4 sides .

There are 2 length and 2 breadth in Rectangle .

• Perimeter of Rectangle = Sum of length of its side.

Putting the given value we get

➻ Perimeter of Rectangle = 2 Length + 2 Breadth

➻ Perimeter of Rectangle = 2l + 2b

Taking Common as 2

➻ Perimeter of Rectangle = 2 ( l + b)

• Hence, the perimeter of the rectangle is 2( l + b) .

Answer 2

❒ Given :-

• ➵ Find the perimeter of a rectangle ,with its length l and breadth b.

❒ To Find :-

• ➵ Perimeter .

❒ Solution :-

⇝Let :

• Length of rectangle = l
• Breadth of rectangle = b

✏There are l and b :

There are 2 lengths and 2 breadths in a rectangle.Hence ,

${\bf{2 \times l + 2 \times b }}$

✏It can be written as :

${\large{\green{:{\longmapsto{\red{\underline{\overline{\bf{2(L + B)}}}}}}}}}$

❒ Hence :-

${\large{\purple{\underline{\red{\underline{\pink{\mathfrak{Perimeter = 2(L + B)}}}}}}}}$
