Question

. Find the perimeter of a rectangle whose
(a) length = 5 cm, breadth = 2.5cm​

Answer 1

Answer:

Step-by-step explanation:

=7.5×2=15 cm

Answer 2

Before, finding the answer. Let's find out on how we can find the answer.

• To find the Perimeter of Rectangle we should use the formula of :

$\boxed{ \sf Perimeter \: of \: Rectangle = (2 \times l + 2 \times b) }$

Where,

L = Length

B = Breath

• First, we must multiply length with 2.
• Then, we must multiply breath with 2.
• And at last we must add both.

Given :

Length = 5 cm

Breadth = 2.5 cm

To find :

Perimeter of Rectangle

Formula Used :

(2 × l) + (2 × b)

Solution :

We know that,

Perimeter of Rectangle = (2 × l) + (2 × b)

= (2 × 5) + (2 × 2.5)

= 10 + 5 cm

= 15 cm

Hence, the Perimeter of Rectangle is 15 cm.
