Question

1.
Find the perimeter:
a. Length = 4 cm, Breadth = 2 cm​

Answer 1

Answer:

Given length- 4cm

breadth - 2cm

formulae  of perimeter =2*l+b

2(4+2)= 12cm

Step-by-step explanation:

Answer 2

Given:

Length of the rectangle = $4\:cm$

Breadth of the rectangle = $2\:cm$

To find:

The perimeter of the rectangle.

Solution:

We know that,

Perimeter of a rectangle = $2(length\:+\:breadth)$

$= 2(4 \: cm + 2 \: cm)$

$= 2 \times 6 \: cm$

$= 12 \: cm$

Therefore, the perimeter of the rectangle is $\boxed{ 12\:cm }$.
